Abstract ：
Localized accumulation of carriers frequently induces corrosion on the surfaces of photocatalysts, restricting the efficacy of photocatalytic technology. The development of a strategy that precisely targets and transforms passivated corrosion regions into reactive sites holds significant potential, yet remains technically challenging. Herein, an advanced microscopy study reveals that BiOBr photocatalysts are susceptible to severe photo-corrosion, leading to a continual thickening of Bi2O3 crystalline films as the photo-oxidation products accumulate on the photocatalytic surfaces. Through a metal cation intercalation process, it is demonstrated that the passivated Bi2O3 films are precisely targeted by the accumulated holes and in situ converted to MxBiyOz (M = Co, Mn, Fe, Pb) nanobeads that act as co-catalysts to expedite charge transfer and enhance photostability. This work deepens the understanding of the atomistic photocorrosion mechanism of BiOBr photocatalysts and contributes to a versatile surface-targeted photochemical modification approach to tackle widespread photocorrosion challenges. © 2025 Wiley-VCH GmbH.

Abstract ：
Photo-/electro-catalytic CO2 reduction with H2O to produce fuels and chemicals offers a dual solution to address both environmental and energy challenges. For a long time, catalyst design in this reaction system has primarily focused on optimizing reduction sites to improve the efficiency or guide the reaction pathway of the CO2 reduction half-reaction. However, less attention has been paid to designing activation sites for H2O to modulate the H2O dissociation half-reaction. Impressively, the rate-determining step in overall CO2 reduction is the latter, and it influences the evolution direction and formation energy of carbon-containing intermediates through the proton-coupled electron transfer process. Herein, we summarize the mechanism of the H2O dissociation half-reaction in modulating CO2 reduction performance based on cutting-edge research. These analyses aim to uncover the potential regulatory mechanisms by which H2O activation influences CO2 reduction pathways and conversion efficiency, and to establish a mechanism-structure-performance relationship that can guide the design and development of high-efficiency catalytic materials. A summary of advanced characterization techniques for investigating the dissociation mechanism of H2O is presented. We also discuss the challenges and offer perspectives on the future design of activation sites to improve the performance of photo-/electro-catalytic CO2 reduction.

Abstract ：
Heterogeneous photoelectrocatalysis systems have recently seen significant growth in organic transformations, but are limited by the inherent physicochemical properties of electrode materials. To enhance selectivity in these processes, we propose an innovative advancement in the rational design of photoanodes. Specifically, we incorporated cobalt porphyrin co-catalysts with confined Co sites onto bismuth vanadate films as a photoanode. This photoanode significantly enhances the efficacy of styrene epoxidation, achieving selectivity and conversion rates of 90 % and 99 %, respectively. Notably, the reaction utilizes water as the sole oxygen source, operates at room temperature, and is easily scalable for gram-scale synthesis. The developed photoanode demonstrates robust performance across various alkene substrates. Operando characterizations reveal that during the epoxidation reaction, the confined Co sites within the porphyrin structure catalyze the oxidation of H2O to form Co-O*, serving as critical intermediates that facilitate cyclization reactions via one-electron processes. This study introduces an innovative heterogeneous photoelectrocatalysis strategy with customizable active sites tailored for selective catalytic organic transformations.

Abstract ：
The oxygen reduction reaction (ORR) can proceed through either a two- or four-electron pathway, both of which are important for a wide range of applications. The intermediate conversion of *O-2(-) + H+ -> *OOH recognized as the rate-determining step in ORR, with its efficiency strongly dependent on the nature of active sites at the surface of a catalyst. Herein, Si-supported carbon dots (Si-CDs) are introduced as cocatalysts in a photocatalytic system, where their nitrogen-carbon sites play a pivotal role in lowering the energy barrier for *OOH formation by promoting proton and electron transfers, thus enhancing the H2O2 production rate in ORR. This strategy is broadly applicable across a wide range of photocatalysts, both with and without use of sacrificial agents. The H2O2 production rate for Zn0.5Cd0.5S (30 mg) increased from 13.0 to 40.9 mu mol h(-1) when 0.6 mg of Si-CDs were added. In-situ characterizations and theoretical simulations are conducted to reveal the reaction pathway and the reduced energy requirements for the *O-2(-) + H+ -> *OOH conversion. This study provides a unique example of overcoming a key barrier in ORR using a metal-free catalyst and promotes potential applications in various fields.

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 ：
Photocatalytic CO2 reduction coupled with H2O oxidation has been pursued extensively, albeit facing challenges in efficiency and selectivity. Herein, we develop a PdSAs+NPs/PTI catalyst by co-anchoring atomic and nanoparticulate Pd species on poly(triazine imide) crystals, which exhibits high activity, selectivity, and stability for CO2 reduction to CO using H2O as the reductant. Combined experimental and theoretical studies reveal that the dual Pd species synergistically enhance charge separation and transfer while promoting CO2 activation, CO desorption, and H2O dissociation. Photo-stimulated electrons migrate to Pd nanoparticles to reduce CO2, and holes oxidize Pd2+ sites to Pd4+ species that catalyze H2O splitting to OH* and H*. The resulting H* spills onto adjacent Pd nanoparticles to support proton-coupled CO2 reduction, whereas OH* is oxidized by Pd4+ to evolve O2, regenerating Pd2+, and closing the catalysis cycle. Importantly, the photoinduced Pd4+ sites dynamically modulate the local adsorption environment, weakening *CO binding on nearby Pd nanoparticles. This facilitates *CO desorption and hampers its hydrogenation to CH4, enabling high CO selectivity. The optimal catalyst achieves a CO yield rate of 22.2 mmol gPd−1 h−1 with 95.7% selectivity, stably operating over 30 h. © 2025 Wiley-VCH GmbH.

Abstract ：
Photocatalytic CO2 conversion with H2O to carbonaceous fuels is a desirable strategy for CO2 management and solar utilization, yet its efficiency remains suboptimal. Herein, efficient and durable CO2 photoreduction is realized over a Ru-NPs/Ru-PHI catalyst assembled by anchoring Ru single atoms (SAs) and nanoparticles (NPs) onto poly(heptazine imide) (PHI) via the in-plane Ru-N-4 coordination and interfacial Ru-N bonds, respectively. This catalyst shows an unsurpassed CO production (32.8 mu mol h(-1)), a record-high apparent quantum efficiency (0.26%) beyond 800 nm, and the formation of the valuable H2O2. Ru SAs tune PHI's electronic structure to promote in-plane charge transfer to Ru NPs, forming a built-in electron field at the interface, which directs electron-hole separation and rushes excited electron movement from Ru-PHI to Ru NPs. Simultaneously, Ru SAs introduce an impurity level in PHI to endow long-wavelength photoabsorption, while Ru NPs strengthen CO2 adsorption/activation and expedite CO desorption. These effects of Ru species together effectively ensure CO2-to-CO conversion. The CO2 reduction on the catalyst is revealed to follow the pathway CO2 -> *CO2 -> *COOH -> *CO -> CO, based on the intermediates identified by in situ diffuse reflectance infrared Fourier transform spectroscopy and further supported by density functional theory calculations.

Abstract ：
Thermocatalytic nonoxidative ethane dehydrogenation(EDH)is a promising strategy for ethene produc-tion but suffers from intense energy consumption and poor catalyst durability;exploring technology that permits efficient EDH by solar energy remains a giant challenge.Herein,we present that an oxygen va-cancy(Ov)-rich LaVO4(LaV04-Ov)catalyst is highly active and stable for photocatalytic EDH,through a dynamic lattice oxygen(Olatt.)and Ov co-mediated mechanism.Irradiated by simulated sunlight at mild conditions,LaVO4-Ov effectively dehydrogenates undiluted ethane to produce C2H4 and CO with a con-version of 2.3％.By loading a small amount of Pt cocatalyst,the evolution and selectivity of C2H4 are en-hanced to 275 μmol h-1 g-1 and 96.8％.Of note,LaVO4-Ov appears nearly no carbon deposition after the reaction.The isotope tracked reactions reveal that the consumed Olatt.recuperates by exposing the used catalyst with O2,thus establishing a dynamic cycle of Olatt,and achieving a facile catalyst regeneration to preserve its intrinsic activity.The refreshed LaVO4-Ov exhibits superior reusability and delivers a turnover number of about 305.The Ov promotes photo absorption,boosts ethane adsorption/activation,and accel-erates charge separation/transfer,thus improving the photocatalytic efficiency.The possible photocatalytic EDH mechanism is proposed,considering the key intermediates predicted by density functional theory(DFT)and monitored by in-situ diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS).
