Abstract ：
Photosynthesis of H2O2 from O-2 and H2O with inexhaustible sunlight as an energy source is a promising approach. However, the photocatalytic performance of pristine polymeric carbon nitride (PCN) is extremely restrained due to the rapid recombination of photo-generated electrons and holes, and slow surface reaction processes. Herein, a new strategy is developed to rationally integrate N, S-co-doped carbon (C-NS), and CoS2 on cyano-rich PCN (PCN-Cy) for photosynthesis of H2O2 under ambient conditions. The engineering with cyano groups (electron-withdrawing groups) promotes the bulk charge separation of PCN. Experimental results reveal that the CoS2 co-catalyst not only serves as an electron acceptor to extract charges from the bulk but also functions as an active site to promote the 2-e(-) ORR process. Besides, the N, S-co-doped carbon performs as an electron channel to promote migration of charges at the interface of PCN-Cy and CoS2. Accordingly, the as-synthesized cyano-rich PCN photocatalyst integrated with N, S-co-doped carbon and CoS2 exhibits a remarkable activity of 321.9 mu m h(-1) for photocatalytic production of H2O2, which is 44.9 times higher than that of the pristine PCN.

Abstract ：
Water electrolysis hydrogen production technology directly generates high-purity hydrogen through electrochemical water splitting, serving as a key technology for achieving zero-carbon emission hydrogen production. Alkaline water electrolysis demonstrates marked advantages in efficiency and rapidly developing anode catalysts in an alkaline medium. Nevertheless, the sluggish kinetics of the hydrogen evolution reaction (HER) at the cathode in an alkaline environment constitute a fundamental bottleneck that restricts the extensive application of this technology. Platinum, serving as the benchmark catalyst for the HER, is limited in its large-scale development due to its scarcity and high cost. In comparison, carbon-supported platinum-based catalysts exhibit exceptional HER catalytic activity and stability, driven by their unique electronic architecture and the synergistic effect with the support. In this review, we comprehensively examine the latest progress of carbon-supported platinum-based materials for the alkaline HER, summarize the factors contributing to the slow kinetics of the HER in an alkaline environment, and then focus on the strategies for modifying the carbon substrate and synthesizing carbon-supported platinum-based nanomaterials. Finally, the review critically evaluates existing challenges and proposes targeted research directions to advance Pt-based electrocatalysts for practical alkaline hydrogen evolution systems.

Abstract ：
Lattice oxygen-mediated photocatalytic ethane dehydrogenation represents a sustainable strategy for ethylene production, yet achieving a balance between high productivity, selectivity, and durability remains challenging. Here, we report a defective NiO-300 catalyst, where precisely engineered Ni vacancies activate lattice oxygen by weakening Ni-O bond and improving lattice oxygen mobility. This promotes efficient ethane activation and C-H bonds cleavage through photoinduced hole capture, intensifying ethane dehydrogenation via a light-boosted Mars-van Krevelen mechanism. The NiO-300 catalyst manifests a high ethylene yield of 604.5 mu mol g-1 h-1 with 100% selectivity and stability over 200 cycles. In situ spectroscopic and theoretical studies elucidate the generation of active oxygen species, the evolution of Ni coordination, the formation of key intermediates, and the underlying photocatalytic mechanism. Our findings highlight cation vacancy engineering as a powerful tactic to fully activate lattice oxygen for solar-driven alkene production from alkane dehydrogenation over oxide photocatalysts.

Abstract ：
The rational preparation of efficient and durable electrocatalysts is the key to advancing the development of water electrolysis technology. Noble metal-based materials, such as Pt, Ru, and Ir, have excellent catalytic performance and stability. However, their high cost and low abundance require researchers to explore effective strategies to improve their utilization efficiency. Electrospinning is a facile synthetic method to prepare one-dimensional nanofibers with the desired composition and structure, especially carbon-supported metal-based electrocatalysts with a large specific surface area and high conductivity, through post-processing strategies. This review introduces the recent progress in electrospinning to prepare noble metal-based catalysts for water electrolysis. Specifically, we summarize various strategies for incorporating noble metals into electrospinning nanofibers, as well as their electrocatalytic performance towards hydrogen evolution, oxygen evolution, and overall water splitting. Finally, we propose the opportunities and challenges faced by electrospinning technology in the creation of water electrolysis catalysts, as well as the prospects for future development.

Abstract ：
Lattice oxygen (LO)-mediated photothermal dry reforming of methane (DRM) presents a promising approach to syngas production. However, realizing high DRM efficiency and durability remains challenging due to the difficulty in activating LOs in catalysts. Herein, we demonstrate that partially substituting Fe sites in perovskite ferrite (LaFeO3) by Mn triggers LOs, bestowing the catalyst with superior activity and stability for photothermal DRM after modification with Ru. The Mn exchange induces a charge transfer from La to Mn, which combined with the incoming photoexcited electrons reconstructs the perovskite's electronic structure, weakening the La-O-Mn bonds and facilitating the LO migration. Meanwhile, photogenerated holes migrate to surface LOs, further enhancing their reactivity to mediate DRM. Under light irradiation, the catalyst exhibits an outstanding syngas production rate (H2: 42.89 mol gRu -1 h-1, CO: 54.92 mol gRu -1 h-1) while stably operating over 150 h. It also achieves a methane turnover frequency of 0.9 s-1 and a light-to-chemical energy efficiency of 15.3%, setting a benchmark for light-driven DRM performance. This work underscores the significance of exact site doping in metal oxides to fine-tune LO activity, providing valuable guidance for fabricating efficient catalysts for solar-powered redox reactions proceeded via the light-supported Mars-van Krevelen mechanism.

Abstract ：
Polymeric carbon nitrides (PCNs), usually the melon phase, have been extensively applied as photocatalysts for CO2 reduction; however, their performance is still unsatisfactory. The condensed allotrope, namely, poly(triazine imide) (PTI) with extended conjugation and a crystallized structure, indeed holds more favorable compositional and structural advantages for photocatalytic CO(2)reduction but remains to be fully exploited. Herein, hexagonal prism-shaped PTI crystals were synthesized and developed as a high-performance photocatalyst for CO2 reduction. With Co(bpy)(3) (2+) as a cocatalyst, the PTI crystals exhibit a CO evolution rate of 44 mu mol h(-1) (i.e., 1467 mu mol g(-1) h(-1)) with 93% selectivity, markedly superior to that of the melon counterpart. Moreover, PTI crystals manifest an apparent quantum efficiency of 12.9% at 365 nm, representing the state-of-the-art value by PCN photocatalysts for CO2-to-CO reduction without using noble metals. The surface pyridine N species of PTI are exposed as active sites to dominate CO2 activation and conversion, which, together with the high crystallinity to facilitate charge separation and transport, endows high CO2 reduction efficiency. In situ diffuse reflectance infrared Fourier transform spectroscopy determines the key intermediates during the CO2 reduction reaction and, consequently, constructs the possible reaction mechanism.

Abstract ：
Decorating Rh cocatalysts with Cr2O3 overlayers can enhance the performance of photocatalytic overall water splitting (POWS). However, there is a general concern on the dissolution of Cr2O3, calling for the development of environment-friendly metal oxides. Here, we employ phenylphosphonic acid (PPOA) as a model surface modifier to decorate the model Rh@CeO2 cocatalysts and demonstrate the critical role of organic surface passivation in H2 evolution catalysis. We identify a “surface passivation effect” in photocatalysis, wherein the PPOA modification on CeO2 overlayers not only suppress the adsorption and activation of oxygen but exhibit strong resistance to hydrogen reduction during POWS. This dual functionality effectively suppresses the reverse reactions by blocking the redox cycle of exposed Rh sites and defective CeO2 overlayers, resulting in significantly enhanced photocatalytic activity and stability. Importantly, this strategy is not limited to Rh@CeO2-PPOA systems; it also improves POWS performance in systems where other reducible oxides-organophosphonic acids structure are used as passivation layers on other noble metal cocatalysts. These findings provide fundamental insights into the universal principles of surface passivation in photocatalysis and offer a practical framework for regulating the reverse reactions and provide guidance for optimizing POWS through targeted surface organic modification. © 2025 Wiley-VCH GmbH.

Abstract ：
Among the current industrial hydrogen production technologies, electrolysis has attracted widespread attention due to its zero carbon emissions and sustainability. However, the existence of overpotential caused by reaction activation, mass/charge transfer, etc. makes the actual water splitting voltage higher than the theoretical value, severely limiting the industrial application of this technology. Therefore, it is particularly important to design and develop highly efficient electrocatalysts to reduce overpotential and improve energy efficiency. Among the various synthesis methods of electrocatalysts, electrochemical synthesis stands out due to its simplicity, easy reaction control, and low cost. This review article classifies and summarizes the electrochemical synthesis techniques (including electrodeposition, electrophoretic deposition, electrospinning, anodic oxidation, electrochemical intercalation, and electrochemical reconstruction), followed by their application in the field of water electrolysis. In addition, some challenges currently faced by electrochemical synthesis in electrocatalytic hydrogen production, and their potential solutions are discussed to promote the practical application of electrochemical synthesis in water electrolysis.Graphical AbstractThis review summarizes and classifies commonly used electrochemical synthesis techniques, followed by the application of electrochemical synthesis methods in research on water electrolysis. Additionally, some challenges faced by electrochemical synthesis in the field of water electrolysis and possible solutions are discussed.

Abstract ：
The industrially important selective hydrogenation of alpha,beta-unsaturated aldehydes to allyl alcohol is still challenging to realize using heterogenous hydrogenation catalysts. Supported Cu catalysts have shown moderate selectivity, yet low activity for the reaction, due to the electronic structure of Cu. By anchoring atomically dispersed Pd atoms onto the exposed Cu surface of Cu@CeO2, we report in this work that hydrogen spillover activates the inert metal-oxide interfaces of Cu@CeO2 into highly effective and selective catalytic sites for hydrogenation under mild reaction conditions. The as-prepared catalysts exhibit much higher catalytic activity in the selective hydrogenation of acrolein than Cu@CeO2. Comprehensive studies reveal that atomically dispersed Pd species are critical for the activation and homolytic splitting of H2. The activated H atoms easily spill to the Cu-O-Ce interfaces as Cu-H delta-and interfacial Ce-O-H delta+ species, making them the active sites for hydrogenation of polar C=O bonds. Moreover, the weak adsorption of allyl alcohol on the Pd and Cu-O-Ce interfacial sites prevents deep hydrogenation, leading to selective hydrogenation of several alpha,beta-unsaturated aldehydes. Overall, we demonstrate here a synergic effect between single atom alloy and the support for activation of an inert metal- oxide interface into selective catalytic sites.

Abstract ：
Single-atom alloys (SAAs) are promising catalysts due to their unique electronic/geometric structures and high atomic efficiency, yet precise control of guest metal atoms and host nanoparticle dispersion remains challenging. This study develops a facile ion exchange-pyrolysis strategy to synthesize ultrafine NiRu SAA nanoparticles confined in porous carbon (NiRu/C) nanosheet arrays. Advanced characterization confirms isolated Ru atoms anchored on Ni nanoparticles with electron transfer from Ni to Ru, achieving uniform dispersion in ultrathin carbon. Theoretical analysis indicates that Ru single atoms optimize reactant adsorption and reduce energy barriers for rate-determining steps, enhancing both hydrogen and oxygen evolution. As bifunctional electrodes in anion-exchange membrane water electrolyzers, NiRu/C demonstrates a low voltage of 1.75 V at 1 A cm-2 at 60 degrees C with 350 h stability, showcasing SAAs' potential for efficient green hydrogen production.
