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 ：
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.

Abstract ：
The doping of metals onto the inorganic non-metallic catalyst g-C3N4 facilitates the reduction of CO2 to C1 and C2 products, representing an effective method for reducing atmospheric carbon dioxide and mitigating global warming. This paper investigates the stability and catalytic activity of g-C3N4 doped with Fe, Co, Ni, and Cu using density functional theory (DFT). The optimal reduction pathways of CO2 at different metal sites are analyzed. The results show that bimetallic doping exhibits a synergistic effect compared to traditional metal doping, significantly enhancing the visible light response range of g-C3N4, promoting the adsorption and activation of CO2, and lowering the Gibbs free energy barrier of the reduction intermediates. Of the materials studied, Co2@g- C3N4 and Ni2@g-C3N4 require higher energy and show poor CO2 activation performance. In contrast, Fe2@g- C3N4's site1 and site2 display superior catalytic performance with activation energy barriers of 0.74 eV and 0.78 eV, respectively. Cu2@g-C3N4, on the other hand, shows favorable performance only at site1, with an activation energy barrier of 0.63 eV. This catalyst is expected to serve as an effective tool for CO2 reduction, providing a new strategy for the design and development of more efficient and selective CO2 reduction catalysts.

Abstract ：
MXene species have emerged as a class of compelling electrode materials in the field of capacitive deionization (CDI). However, as an excellent member of the MXene family, the Nb4C3Tx has not received much attention in terms of CDI. Herein, we have not only established the feasibility of Nb4C3Tx as a potential desalination electrode materiel but also proposed a wrinkle-engineering strategy that can effectively improve the CDI performance of Nb4C3Tx freestanding membranes. Specifically, the introduction of wrinkles on Nb4C3Tx nanosheets contributes to optimizing the interlayer space, accessibility, conductivity, stability, and CDI performance of the assembled membranes. In particular, the optimized wrinkled Nb4C3Tx membranes can achieve an ultrahigh desalination capacity of similar to 188.2 mg g(-1) at 1.6 V accompanied by a fast adsorption rate of similar to 12.6mg g(-1) min(-1), showing great competitiveness with other MXene individual electrodes. In addition, the as-designed electrodes also exhibit superior cycle desalination stability as well as good applicability to different salts (such as LiCl, KCl, CaCl2, and MgCl2). This work both extends the MXene material applicable to CDI and offers an effective solution for improving the properties of Nb4C3Tx-MXene lamellar membrane electrodes, opening up enormous opportunities for the use of such MXene species in the field of electrochemical desalination.

Abstract ：
The CeO2/CuMoO4 type II heterojunction with varying CeO2 contents was synthesized by the hydrothermal method. These heterojunction catalysts exhibit superior antibacterial activity against both Escherichia coli and Staphylococcus aureus under visible light irradiation compared to CuMoO4 alone. The evaluations of bacterial morphology, intracellular content concentration of bacteria, and reactive oxygen species (ROS) during the photocatalytic process indicated that the ROS oxidize phospholipids in the bacterial cell membrane, which leads to the damage of the cell structure and leakage of cell contents, ultimately resulting in bacterial inactivation. Both EPR (Electron Paramagnetic Resonance) and ROS scavenging experiments confirmed that superoxide radicals (O-2(-)) and e(-) play an important role in the photocatalytic antibacterial activity. The introduction of CeO2 into CuMoO4 enhances the heterojunction's photoelectric performance and promotes the efficient separation of photogenerated carriers, which benefits the production of O-2(-). Furthermore, the Ce3+/Ce4+ redox couple that exists in CeO2 may act as a trap to capture the electron, which inhibits the recombination of electrons and holes, and further reacts with the adsorbed oxygen on the catalyst surface to generateO-2(-). This approach of introducing Ce3+/Ce4+ redox pairs as defect centrals to improve superoxide radicals offers an avenue for modifying photocatalytic materials and provides an alternative way to traditional antibiotic strategies in antibacterial applications.

Abstract ：
Photothermal catalytic N-acetylation of aniline has been a promising strategy to synthesize amides, which combined the advantages of thermal catalysis and photocatalysis. Herein, we demonstrate a high-performance strategy to synthesize amides catalyzed by the in-situ formed first-row transition-metal (Fe, Co, Ni, Mn et al.) complexes nanodots (TMC NDs) under solar light excitation without using noble metals or strong acids. The dualfunctional nitriles substrates acted as the ligands to coordinate with transition-metal salts affording photosensitive TMC NDs with high solar-to-thermal energy conversion efficiency. Intramolecular charge transitions reduced the energy barrier of nitriles activation by weakening C---N bond and triggered near-field temperature rise via the electron-phonon scattering non-radiative pathway. The reaction system exhibited good tolerance to different functional groups, affording a series of amide derivatives. Such a dynamic coordination reaction mode and the in-situ formed TMC NDs opens new avenues toward solar-heat conversion via photon-phonon coupling in the field of chemical synthesis.

Abstract ：
The valorization of native lignin to functionalized aromatic compounds under visible light is appealing yet challenging. In this communication, colloidal mercaptoalkanoic acid capped ultrathin ZnIn2S4 (ZIS) microbelts was successfully fabricated, which was used as a superior catalyst for depolymerization of native lignin in birch woodmeal under visible light, with an optimum yield of 28.8 wt % to functionalized aromatic monomers achieved in 8 h. The capped mercaptoalkanoic acid not only enables a solvent modulated reversible interchange of ZIS between the colloidal state for efficient reaction and the aggregated state for facile separation, but also serves as a precursor for light initiated generation of reactive thiyl radical for highly selective cleavage of beta-O-4 bond in native lignin. This work provides a green and efficient strategy for the depolymerization of native lignin to functionalized aromatic monomers under mild conditions, which involves a new mechanism for the cleavage of beta-O-4 bonds in native lignin. The capability of cleavage of beta-O-4 bonds in native lignin by photogenerated thiyl radicals also demonstrates the great potential of using photogenerated thiyl radicals in organics transformations.

Abstract ：
Converting clean solar energy into chemical energy through artificial photosynthesis is an effective solution to solve the energy and environmental issues. Here, we report a Cs3Bi2Br9/Bi2WO6 (CBB/BWO) Z-scheme heterojunction constructed via electrostatic self-assembly, which facilitates efficient separation of photogenerated carriers and ensures the corresponding redox capacity of both components. By sharing Bi atoms, a Br-Bi-O bond is established between CBB and BWO, serving as an "electron bridge". The electrons generated by BWO are efficiently channeled to CBB through the heterojunction-formed "electron bridge", thereby achieving effective photocatalytic CO2 reduction. Under simulated sunlight conditions, it exhibits the highest CO yield of 72.52 mu mol g(-1) (without the addition of any precious metal, photosensitizers or sacrifices), which is approximately 7-fold and 18-fold greater than that of pure CBB and BWO, respectively. This work provides a more profound comprehension of the regulation of electron transfer through interfacial chemical bonds, thereby proposing a promising strategy for the development of efficient heterojunction photocatalysts for CO2 photoreduction.

Abstract ：
Prussian blue analogues (PBAs) have been widely studied as cathodes for potassium-ion batteries (PIBs) due to their three-dimensional framework structure and easily adjustable composition. However, the phase transition behavior and [Fe(CN)(6)](4-) anionic defects severely deteriorate electrochemical performances. Herein, we propose a defect-free potassium iron manganese hexacyanoferrate (K1.47Fe0.5Mn0.5[Fe(CN)(6)]1.26H(2)O, KFMHCF-1/2) as the cathode material for PIBs. The Fe-Mn binary synergistic and defect-free effects can inhibit the cell volume change and octahedral slip during the K-ion insertion/extraction process, so that the phase transformation behavior (monoclinic <-> cubic) is effectively inhibited, achieving a zero-strain solid solution mechanism employing Fe and Mn as dual active-sites. Thus, KFMHCF-1/2 contributes the highest initial capacity of 155.3 mAhg(-1) with an energy density of 599.5 Whkg(-1) at 10 mAg(-1) among the reported PBA cathodes, superior rate capability, and cyclic stability over 450 cycles. The assembled K-ion full battery using K deposited on graphite (K@G) as anode also delivers high reversible specific capacity of 131.1 mAhg(-1) at 20 mAg(-1) and ultralong lifespans over 1000 cycles at 50 mAg(-1) with the lowest capacity decay rate of 0.044% per cycle. This work will promote the rapid application of high-energy-density PIBs.

Abstract ：
The electrocatalytic conversion of inert CO2 to value-added chemical fuels powered by renewable energy is one of the benchmark approaches to address excessive carbon emissions and achieve carbon-neutral energy restructuring. However, the adsorption/activation of supersymmetric CO2 is facing insurmountable challenges that constrain its industrial-scale applications. Here, this theory-guided study confronts these challenges by leveraging the synergies of bimetallic sites and defect engineering, where pyrochlore-type semiconductor A(2)B(2)O(7) is employed as research platform and the conversion of CO2-to-HCOOH as the model reaction. Specifically, defect engineering intensified greatly the chemisorption-induced CO2 polarization via the bimetallic coordination, thermodynamically beneficial to the HCOOH production via the *HCO2 intermediate. The optimal V-BSO-430 electrocatalyst with abundant surface oxygen vacancies achieved a superior HCOOH yield of 116.7 mmol h(-1) cm(-2) at -1.2 V-RHE, rivalling the incumbent similar reaction systems. Furthermore, the unique catalytic unit featured with a Bi-1-Sn-Bi-2 triangular structure, which is reconstructed by defect engineering, and altered the pathway of CO2 adsorption and activation to allow the preferential affinity of the suspended O atom in *HCO2 to H. As a result, V-BSO-430 gave an impressive FEHCOOH of 93% at -1.0 V-RHE. This study held promises for inspiring the exploration of bimetallic materials from the massive semiconductor database.
