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 ：
Photocatalysis technology holds great potential in converting CO2 into value-added chemicals and fuels, playing a significant role in achieving carbon neutrality and promoting carbon cycling. However, the low charge carrier separation efficiency of existing photocatalysts limits their performance in CO2 utilization. Herein, a novel Sscheme structured 2D/2D WO3/InVO4 composite is successfully synthesized via hydrothermal method, which maintains the high selectivity for converting CO2 to CO under visible light without the need for noble metal cocatalysts or sacrificial agents. The optimized WO3/InVO4 composite exhibits CO yields of 13.37 mu mol/g, which is 3.36 times higher than that of InVO4. Enhancement in photocatalytic performance is primarily attributed to the meticulously designed S-scheme heterojunction structure, which effectively achieves spatial separation of photogenerated charges. Furthermore, the intimate contact between 2D WO3 and 2D InVO4 enhances charge transfer efficiency. This work offers valuable insights for the design and construction of novel S-scheme heterojunction photocatalysts.

Abstract ：
Mimicking photosynthesis to convert CO2 and H2O into value-added chemicals represents an optimal approach to mitigate energy shortages and environmental pollution, and the development of highly efficient and selective photocatalysts for CO2 to CO conversion is essential for the effective utilization of CO2 resources. Herein, a novel 2D@0D InVO4@MnWO4 S-scheme heterojunction composite is successfully developed via an in situ hydrothermal method, achieving the conversion of CO2 into CO under visible light irradiation using H2O as a reducing agent, without any noble metal cocatalysts or sacrificial reagents. The CO generation rate over the optimal InVO4@MnWO4 composite reaches 6.20 mu mol g-1 h-1, which is approximately 4.50 times than that of InVO4. The enhanced photocatalytic performance is ascribed to the charge separation facilitated by the formation of an S-scheme heterojunction between InVO4 and MnWO4. This work is expected to provide a new insight for the design of highly selective photocatalysts for the conversion of CO2 to CO.

Abstract ：
Employing photocatalytic technology to transform CO2 into valuable fuels is considered a promising solution for addressing the exacerbated greenhouse effect and energy crisis. The development of photocatalysts featuring superior charge separation efficiency is pivotal for the widespread implementation of photocatalytic CO2 reduction technologies. Herein, zero-dimensional (0D) NixP nanoparticles are anchored onto two-dimensional (2D) LaTiO2N nanosheets by a photo-deposition method, and a NixP/LaTiO2N Schottky junction composite with excellent photocatalytic CO2 reduction performance is constructed. The optimal NixP/LaTiO2N composite achieves CO and CH4 yields of 9.39 and 4.15 mu mol g-1 h-1, respectively, with the utilized photoelectron number (UPN) reaching 51.98 mu mol g-1, which is approximately 9.7 times higher than that of LaTiO2N alone. The improved photocatalytic performance of the composites can be attributed to the formation of Schottky junctions, which effectively suppress the recombination of photogenerated carriers. This study provides a new idea for the development of 0D/2D Schottky junction photocatalysts.

Abstract ：
Photocatalytic water splitting on metal oxides often faces oxygen evolution inefficiency, reflecting the complex interplay of its two half-reactions. Strategies like heterojunctions, cocatalyst loading, or noble metal nano- particles addition have been explored to address this. Using gamma- Ga 2 O 3 nanosheets as a model, we uncovered the formation of-O-O- species as the key barrier to stoichiometric splitting. To tackle this, a strategy was devised, Sr-doping to inhibit surface peroxidation. The resultant Sr-doped gamma- Ga 2 O 3 (Sr-Ga2O3) significantly improved activity and stability, achieving balanced H2 and O2 production under 125 W mercury lamp light. Upon further enhancement with Rh/Cr2O3 cocatalyst via photoreduction, the Sr-Ga2O3/(Rh/Cr2O3) composite demonstrated a remarkable 173.3 mu mol & sdot;h-1 H2 and 86.7 mu mol & sdot;h-1 O2 evolution rate, 8.0 times higher than gamma- Ga 2 O 3 alone, with a 34.1 % quantum efficiency under 260 nm light. This represents a record performance for Ga2O3-based photo- catalytic water splitting. Mechanistically, Sr doping alters surface chemistry to favor direct oxygen release. Our study elucidates molecular-level insights into non-stoichiometric splitting mechanisms and offers a potent strategy to boost metal oxide photocatalysts' water-splitting efficiency.

Abstract ：
In heterogeneous photocatalysis, the dynamics of charge carriers holds particular significance for comprehending the underlying catalytic mechanism and designing highly efficient photocatalysts. The current technological challenge lies in how to maximize the behavior of carriers and enable them to unleash their potential in photocatalytic reactions. Herein, we present a novel Prussian blue analogue (PBA)-derived InFe-based oxide (denoted as InFe-x), which features internal Fe doping and an external crystalline/amorphous heterojunction, serving as an effective photocatalyst for photocatalytic reverse water gas shift (RWGS) reactions. Experiments and theoretical simulations have confirmed that doping Fe into In2O3 can alter the electronic and energy structure and achieve the spin polarization effect, thereby enhancing the intrinsic carrier generation and separation behavior; meanwhile, the formed Fe-In2O3/Fe2O3 S-scheme heterojunction establishes an internal built-in electric field and creates a new transport pathway for photogenerated carriers, which significantly inhibit the inherent photogenerated electron-hole recombination. Therefore, this "internal and external cultivation" strategy can fundamentally optimize and maximize the behavior of charge carriers, thereby significantly enhancing the photocatalytic CO2 hydrogenation performance.

Abstract ：
The photocatalytic nonoxidative coupling of methane (CH4) is crucial for sustainable energy production and chemical synthesis, however, a key challenge in advancing this process lies in the development of efficient and highly selective catalytic systems. In this study, we employ an in situ thermally induced strategy to promote the in-situ growth of oxygen vacancies (VO) for constructing a high-density In-VO-In-OH frustrated Lewis pairs (FLP) on Ag/In(OH)3-InOOH (Ag/InOxHy). Our results demonstrate that FLP can effectively polarize C-H bonds, while Ag nanoparticles serve as electron acceptors, significantly reducing the recombination of photogenerated carriers and enhancing the catalytic performance of methane coupling. Benefiting from the high density of FLP and photothermal synergistic effect, we achieve a remarkable C2H6 yield of 339.2 mu mol gcat flow methane atmosphere. Notably, in-situ electron paramagnetic resonance analysis not only validates this innovative strategy but also reveals a new mechanism of oxygen vacancy recycling which showcases its great potential to advance other photocatalytic processes.

Abstract ：
Photocatalytic CO2 reduction comprises two coupled half-reactions: CO2 reduction and H2O oxidation. Efficient coupling of these reactions maximizes the utilization of photogenerated electrons and holes, enhancing CO2 conversion and product selectivity. In this study, sulfur-deficient VS-Zn3In2S6 (VS-ZIS) catalysts were synthesized via an ethylene glycol solvothermal method, followed by anchoring Fe single-atom sites (Fe/VS-ZIS) to facilitate CO2 photoreduction using H2O as proton source. The 1 %Fe/VS-ZIS exhibited exceptional performance, with a CO production rate of 88.6 μmol·g−1·h−1 and 97 % selectivity. Experimental and DFT results revealed that VS functioned as reductive sites to strengthen CO2 adsorption and activation, while Fe single atoms (SAs) served as oxidative sites to facilitate H2O dissociation for proton supply. Fe SAs also induced spin polarization to enhance IEF, thereby suppressing photogenerated charges recombination at redox sites. Meanwhile, Fe SAs reduced COOH* formation energy barrier and lowered CO desorption temperature, improving CO selectivity. The constructed dual active sites synergistically enhanced the overall photocatalytic CO2 reduction performance. This work offers new technical pathways for designing redox dual-active sites to boost the overall photocatalytic CO2 reduction efficiency. © 2025 Elsevier B.V.

Abstract ：
CH3OH is the most desired product of photocatalytic CH4 conversion. The prominent metal-decorated photocatalyst is challenging in both high yield and selectivity for CH3OH products due to over-oxidation by center dot OH mechanism. Here, interstitial Zn is fabricated into ZniO to induce the formation of Zn atom island for rapid single electron reduction of O2 into center dot OOH instead of center dot OH for the selective combination with methyl into CH3OOH. AuPd alloy is simultaneously decorated on ZniO surface for tuning CH3OOH adsorption and reduction into CH3OH. The synergy of Zn atom island and AuPd alloy achieve a tandem reaction pathway (CH4 -> CH3OOH -> CH3OH) for an unprecedented CH3OH yield of 2444 mmol gAuPd-1 h-1 (or 8800 mu mol gcat-1 h-1) with 98.3% selectivity, which bypasses the center dot OH mechanism for tuning the high selectivity of CH3OH. An apparent quantum efficiency of 18.53% at 370 nm for CH4 conversion are super to the reported photocatalytic systems. Thus, this work provides the new strategy of the synergetic atom island and metal alloy photocatalysts through a tandem reaction pathway to mediate the photocatalytic selective oxidation of CH4 into the desired CH3OH.

Abstract ：
Two dimensional (2D) nanosheet photocatalysts have received intensive attention for various incomparable advantages. However, fabricating single-atom-thick photocatalyst nanosheets remains challenging. In this work, we developed monolayer nanosheets of Ti0.91O2 photocatalysts via the hydrazine assisted hydrothermal exfoliation of multilayer nanosheets. The hydrazine hydrate used for exfoliation can simultaneously serve as a sacrificial agent. Thepristine monolayer Ti0.91O2 photocatalysts achieved a hydrogen production rate of 6.22 mmol h-1 g-1 from water splitting, representing a fourfold enhancement over multilayer nanosheets. Upon loading Pt nanoparticles, the hydrogen production activity of Ti0.91O2 monolayer nanosheets increased to 13.28 mmol h-1 g-1. The monolayer nanosheets of Ti0.91O2 photocatalysts markedly enhanced the separation efficiency of photogenerated charge carriers. Furthermore, we demonstrate that the photogenerated electrons migrate to the edge of Ti0.91O2 monolayer nanosheets for the reduction reaction, while the photooxidation occurred on the surface of the nanosheets. This study provides valuable insights into the design of nanosheet photocatalysts.
