Abstract :

Conjugated microporous polymers (CMPs) have emerged as a class of promising organic photocatalysts due to their tailorable polymer monomers, tunable molecular orbitals, diverse synthesis strategies, etc. However, as with most single photocatalysts, even finely designed CMPs are still subject to the recombination of photogenerated carriers, making it difficult to perform photocatalysis effectively. Herein, two types of CMPs containing pyrazine and benzothiadiazole units (labeled as PzTP and BTTP, respectively) are purposely designed and successfully assembled them into hierarchical hollow spheres (PzTP@BTTP) by sequential polymerization on sacrificial templates. It is demonstrated that these two CMPs with matched orbital energy level structures effectively form a Z-scheme heterojunction with photoelectronic properties superior to those of a single CMP. Particularly, the PzTP@BTTP hollow heterojunction CMP is capable of generating H2O2 as high as 8.19 mmol g−1 h−1 in pure water under blue light irradiation, and even 20.49 mmol g−1 h−1 using benzyl alcohol as a hole sacrificial agent, exhibiting great competitiveness in this field. This work suggests that it is feasible to construct efficient heterojunction photocatalysts by rationally combining CMPs with different energy level structures, which opens up new avenues for expanding the research of CMP-involved organic semiconductors in the photocatalysis area. © 2025 Wiley-VCH GmbH.

Abstract :

The precise regulation of photocatalytic oxygen reduction reaction (ORR) pathways, particularly the more energy-efficient one-step 2e(-) route, is of fundamental importance for optimizing H2O2 production efficiency in rationally designed covalent organic frameworks (COFs). Here, a strengthened donor-acceptor (D-A) structured TPCN-COF [COF synthesized from 2,4,6-hydroxy-1,3,5-benzotricarboxaldehyde and 1,3,5-tris (4-aminophenyl) benzene] photocatalyst was developed through the strategic incorporation of pyridine nitrogen moieties into the COF skeleton. The strengthened D-A structure facilitates effective separation of photogenerated charge carriers while promoting rapid electron transfer kinetics. Concurrently, the introduced pyridine nitrogen units increase the surface polarity, thereby improving hydrophilicity and enabling more efficient proton delivery to active sites. Remarkably, the synergistic combination of enhanced charge separation and optimized proton transport in TPCN-COF effectively shifts the ORR mechanism from two-step 1e(-) pathway to one-step 2e(-) process. As a result, TPCN-COF achieves an exceptional H2O2 production rate of 1320.9 mu molg(-1)h(-1) under visible light irradiation (lambda >= 420 nm) in an air-equilibrated aqueous system, representing a nearly 3-fold enhancement compared to the unmodified TPCC-COF [COF synthesized from 2,4,6-hydroxy-1,3,5-benzotricarboxaldehyde and 5,5 ',5 ''- (benzene-1,3,5-triyl) tris (pyridin-2-ylamino)]. This work establishes an effective design strategy for constructing COFs photocatalysts with strong D-A structures, and elucidates the synergistic regulatory mechanism, by which both electronic structure and surface properties govern ORR pathway selectivity in COF-based systems.

Abstract :

Hydrogen peroxide (H2O2) is a crucial, eco-friendly oxidizing agent with a wide range of industrial, environmental, and biomedical applications. Traditional production methods, such as the anthraquinone process, face significant challenges in terms of energy consumption and environmental impact. As a sustainable alternative, photocatalytic H2O2 production, driven by solar energy, has emerged as a promising approach. This review discusses the key advancements in photocatalytic H2O2 synthesis, focusing on overcoming challenges such as charge recombination, selectivity for the two-electron oxygen reduction reaction (2e- ORR), and catalyst stability. Recent innovations in photocatalyst design, including high-entropy materials, single-atom catalysts, and covalent organic frameworks (COFs), have significantly enhanced efficiency and stability. Furthermore, novel strategies for optimizing charge separation, light harvesting, and mass transfer are explored. The integration of artificial intelligence and bioinspired systems holds potential for accelerating progress in this field. This review provides a comprehensive overview of current challenges and cutting-edge solutions, offering valuable insights for the development of scalable, decentralized H2O2 production systems that contribute to a more sustainable future.

Regioisomeric control of planarity enhances exciton dissociation in conjugated polymers for high-efficiency photocatalytic H2 evolution SCIE

Abstract&Keyword Cite

Abstract :

Organic conjugated polymers (CPs) are promising photocatalysts for solar-to-hydrogen conversion, yet their efficiency is often limited by large exciton binding energies and poor charge separation. In this study, we report a molecular isomerization strategy to control polymer planarity and thereby enhance exciton dissociation and photocatalytic activity. Two isomeric CPs, Pyrene-Thiophene-Benzothiazole (Py-T-BT) and Pyrene-Thiophene-iso-Benzothiazole (Py-T-isoBT), were designed and synthesized, employing pyrene as the donor, thiophene as the pi-bridge, and either benzothiadiazole (BT) or its structural isomer (isoBT) as the acceptor. The introduction of the isoBT unit induced steric hindrance, resulting in Py-T-isoBT exhibiting significantly reduced molecular planarity (dihedral angles of 30.3 degrees and 9.2 degrees) compared to the highly planar Py-T-BT (dihedral angle of 4.2 degrees). Theoretical calculations and experimental characterization confirmed that the more planar Py-T-BT possessed a narrower band gap, a larger transition dipole moment, and consequently a significantly lower exciton binding energy. Time-resolved spectroscopy revealed that Py-T-BT enabled ultrafast formation of charge transfer excitons (tau CT = 0.60 ps), in contrast to Py-T-isoBT (tau CT = 3.95 ps). As a result, Py-T-BT demonstrated a photocatalytic hydrogen evolution rate of 7.95 mmol g-1 h-1 with a 3 wt% Pt cocatalyst under visible light irradiation (lambda >= 420 nm), approximately 20 times higher than that of Py-T-isoBT. This work highlights the pivotal role of molecular planarity in modulating exciton dynamics and presents a generalizable strategy for designing high-efficiency polymer photocatalysts through isomeric engineering.

Quantum Tunneling of Photogenerated Charges for Artificial Photosynthesis SCIE

Abstract :

Photocatalytic conversion of CO2 and H2O to high-value chemicals or fuels provides a crucial pathway for efficiently achieving the conversion and storage of solar-to-chemical energy; however, the overall efficiency is severely restricted by the spatial separation of photogenerated charges. The lifetime of charges in a photoexcited semiconductor particle is mismatched utterly with the rate of interfacial redox reactions, locking kinetically the target reactions. To maximize the availability of photogenerated charges for artificial photosynthesis, constructing various types of heterojunctions including Schottky, p-n, and Z/S-scheme is widely used to manipulate the directional migration of photogenerated charges toward surface active sites, where photoredox catalysis proceeds. Even so, it is unavoidable for the recombination of initially separated charges at the interfacial heterojunctions composed of several atomic layers with less than 1.0 nm thickness, where the Coulomb force remains dominant, leading to the quadratic loss of charges on the surface or interface of catalyst particles. How to eliminate the Coulomb confinement for charges has been a highly interesting topic and yet a formidable challenge in the domain of photocatalysis and solar energy conversion.In this Account, aiming to suppress the recombination of initially separated charges, we introduced a novel strategy of charge tunneling separation to design efficient artificial photosystems for CO2 conversion. An insulator is inserted between the semiconductor and metal to form the metal-insulator-semiconductor (MIS) structure, where the charge donor and acceptor are spatially separated by the insulating layer with a thickness of a few nanometers, different completely from the conventional Schottky junction with a direct contact M/S interface. Photoexcitation of the semiconductor unit generates a large population of hot electrons and holes, and then they immediately tunnel to the metal catalyst for redox reactions across the two M/I and I/S interfaces and the insulating layer. The tunneling separation proceeds within a few attoseconds at a mean free path. These tunneled electrons or holes are trapped, concentrated, and localized on the catalytic units consisting of metallic single atoms, nanoclusters (NCs), or nanoparticles (NPs), and thus the emphasis of this Account will be put on three aspects: (1) understanding the physical fundamentals of quantum tunneling of photogenerated charges for artificial photosynthesis, (2) smartly designing the chemical components and structures of functional units including photoabsorbers, insulators, catalytic active centers and interfaces to maximize the tunneling probability, and (3) constructing a MIS-type all-solar-driven artificial photosynthetic system, where the functional units responsible for CO2 reduction and water oxidation are spatially segregated to enable efficient conversion of solar-to-chemical energy. As a result, a solar-to-chemical conversion efficiency (eta SCC) of 13.6% was achieved for the photosynthetic reaction. This work offers guidance for designing novel, high-performance photocatalysts and photoelectrodes and lays the foundation for producing solar fuels at a large scale. Finally, the challenges and outlook for quantum tunneling-based artificial photosynthesis are discussed. Bidirectional tunneling-enhanced artificial leaf technology is expected to facilitate the development of efficient and durable artificial photosystems capable of converting solar energy to fuels and chemicals.

Abstract :

Postoperative abdominal adhesions are the most common complication following abdominopelvic surgery, posing a significant burden on patients, clinicians, and society. However, current physical barriers often involve a tradeoff between preventing these adhesions and inhibiting inflammation. Herein, a one-stone-two-birds strategy is presented to address this challenge through an injectable intertwined hydrogel containing sulfobetaine, modified aminocaproic acid (A6ACA), and ZnO nanoparticles (PSA-ZnO hydrogel). This intertwined network is stabilized by multiple intermolecular coordination bonds, including hydrogen bonds and electrostatic interactions—enabling facile injection and resistance to abdominal creep stress. Experimental results demonstrate that PSA-ZnO hydrogel fully reduce the severity of peritoneal adhesions in treated rats at both 7- and 14-days post-surgery, outperforming commercially available hyaluronic acid (HA) gel due to its superior antifouling, antibacterial (> 95% clearance of E. coli and S. aureus,), hemostatic (55 s), and wound healing properties (IL-6 and TNF-α decreased and VEGF increased). Unlike conventional barriers, PSA-ZnO prevents foreign body formation by inhibiting blood clot organization and pathologic fibrin accumulation at wound sites. This integrated approach offers a clinically translatable solution for complete prevention of postoperative adhesions and inflammation, with the potential to improve patient outcomes and reduce healthcare burdens. © 2025 The Author(s).

Close π-π stacking facilitated intermolecular charge separation in self-assembled perylene monoimide for photocatalytic hydrogen production SCIE

Abstract&Keyword Cite

Abstract :

The tightness of pi-pi stacking in supramolecular organic semiconductors plays a crucial role in governing the spatial separation and migration dynamics of photogenerated charge carriers, ultimately determining their photocatalytic performance. To achieve close pi-pi stacking, the suitable design of molecular structure is essential. Therefore, two isomers of pyridine carboxylic acid-modified perylene monoimide (PMI) were designed and synthesized, namely PM5A and PM6A. In aqueous solution, these molecules self-assemble into aggregates, which exhibit distinct stacking properties and optical characteristics. Upon photoexcitation, the loose pi-pi stacking of PM5A favors the generation of charge-transfer excitons (CTEs) over charge-separation excitons (CSEs). In contrast, PM6A, stabilized by intermolecular hydrogen bonds and possessing close pi-pi stacking, undergoes efficient charge separation (CS) to produce CSEs within 4.5 picoseconds. When incorporated into metal-insulator-semiconductor (MIS) photosystems with polyvinylpyrrolidone (PVP)-capped Pt, the Pt/PVP/PM6A system demonstrates a hydrogen evolution rate (HER) of 8100 mu mol g(-1) h(-1), nearly five times higher than that of the Pt/PVP/PM5A system. Additionally, the maximum apparent quantum efficiency (AQE) reaches approximately 2.1% under irradiation with light of a single wavelength of lambda = 425 nm.

Abstract :

H2 and O2 evolutions occur simultaneously for conventional particulate photocatalytic overall water splitting (PPOWS), leading to a significant backward reaction and the formation of an explosive H2/O2 gas mixture. This is an issue that must be addressed prior to industrialization of PPOWS. Here, a convenient, cost-effective, and scalable concept is introduced to uncouple hydrogen and oxygen production for PPOWS. Based on this idea, a three-component photocatalyst, Co(5 %)-HPCN/(rGO/Pt), is constructed, consisting of a photoresponsive chip (HPCN), a H2 evolution cocatalyst (rGO/Pt), and a cobalt complex capable of reversibly binding O2 (Co), to achieve the decoupling of PPOWS under alternating UV and visible light irradiations. The asynchronous O2 and H2 evolution strategy have considerable flexibility regarding the photocatalyst structure and light sources suitable for PPOWS.

Abstract :

Metal-nitrogen co-doped composite (M-N-C) carbon materials exhibit outstanding catalytic performance in oxygen reduction reactions (ORR), making them promising candidates to replace commercial Pt/C catalysts. However, it remains a challenge to achieve a rational design that ensures a uniform dispersion of the metal active centers in the nitrogen-doped carbon materials and an effective construction of the M-N active sites to enhance the ORR performance. This research introduces an innovative in situ pyrolysis technique utilizing the guanine biomolecule in conjunction with ZIF-67. This approach not only circumvents the pitfalls of structural disintegration and cobalt center agglomeration but also creates an abundance of anchoring sites conducive to the atomic dispersion of cobalt. Consequently, this method fosters the synthesis of Co-N and pyridinic-N active sites, which are pivotal for catalytic activity. The G-Co@NC-800 catalyst demonstrates exceptional ORR catalytic prowess, with a half-wave potential of 0.83 V (vs RHE) and a current density of -5.1 mAcm-2, coupled with remarkable stability and methanol tolerance in alkaline media. These attributes surpass those of commercial Pt/C catalysts, underscoring the superiority of this novel catalyst. This pioneering approach promotes the rational design of uniformly dispersed Co nanoparticles and the extensive construction of Co-N sites. Metal-nitrogen co-doped carbon materials are synthesized via a simple and facile in-situ pyrolysis strategy from biomolecules guanine with ZIF-67.The guanine transferred into 2D carbon nanosheets and nanotubes after pyrolysis, which inhibits the structural collapse and Co centers agglomeration of ZIF-67 during pyrolysis.The guanine provides anchoring sites for the Co nanoparticles (Co-Nx).The uniformly dispersed Co nanoparticles, as well as the widely constructed Co-Nx, provide a large number of active centers for catalytic activity of ORR in alkaline conditions.

Abstract&Keyword Cite Version(2)

Abstract :

This study successfully synthesized selenium-doped CuWO4 photocatalysts via a hydrothermal method and systematically investigated their visible-light-driven antibacterial performance and mechanistic pathways. Experimental results reveal that selenium doping concentration significantly modulates the photocatalytic activity, with the optimal doping level of 0.7 mmol achieving remarkable antibacterial efficiency. Under 100 min of visible-light irradiation, the material achieved 99.9% inactivation of S. aureus at an initial concentration of 107 CFU mL-1. Systematic characterizations, including radical trapping experiments, scanning electron microscopy (SEM), and intracellular genetic material leakage assays, demonstrate that selenium doping introduces electron-trapping centers, effectively suppressing charge carrier recombination. This optimization enhanced the photocatalytic antibacterial activity by 2.3 times compared to pristine CuWO4 and significantly promoted the generation of reactive oxygen species (ROS: (OH)-O-center dot, (center dot)O2-, and 1O2). The resultant ROS disrupt bacterial cell wall integrity via lipid bilayer destruction, induce membrane permeability alterations, and provoke cytoplasmic leakage, collectively leading to efficient bacterial inactivation. This work elucidates the atomic-level mechanism of selenium-enhanced photocatalytic activity in tungstate-based materials and provides fundamental insights for designing advanced semiconductor photocatalysts for antimicrobial applications.
