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 ：
Localized surface plasmon resonance (LSPR) on base-metal nanoparticles holds significant potential for applications in diverse fields owing to its capability for electric field enhancement. Nevertheless, the efficiency of single-energy conversion remains a limiting factor for LSPR applications. This study investigated the utilization of hot carriers, generated through the LSPR effect in copper nanoparticles (Cu NPs) supported on ZrO2, to enhance the performance of the thermal catalytic reverse water-gas shift (RWGS) reaction. Finite difference time domain simulations and Kelvin probe force microscopy (KPFM) tests demonstrated that LSPR induces a strong electric field, facilitating the excitation of hot carriers in Cu NPs. In-situ DRIFTS analysis revealed that hot electrons promote the formation of formate species (HCOO*) and their subsequent transformation into CO, identified as the rate-determining step. Furthermore, in-situ H2 pulse and quasi-in situ EPR analyses indicated that photo-assisted thermal conditions enhance the conversion of H2 into active hydrogen species (H* or H + ) on Cu NPs, promoting the generation of oxygen vacancies and the transformation of intermediates. Constrained density functional theory calculations further demonstrated that visible light irradiation reduces energy barriers, thereby increasing reaction efficiency. The findings provide valuable insights into the contribution of LSPR-induced hot electrons in advancing the RWGS reaction.

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 ：
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 ：
Piezo-photocatalysis is a frontier technology for converting mechanical and solar energies into crucial chemical substances and has emerged as a promising and sustainable strategy for N-2 fixation. Here, for the first time, defects and piezoelectric field are synergized to achieve unprecedented piezo-photocatalytic nitrogen reduction reaction (NRR) activity and their collaborative catalytic mechanism is unraveled over BaTiO3 with tunable oxygen vacancies (OVs). The introduced OVs change the local dipole state to strengthen the piezoelectric polarization of BaTiO3, resulting in a more efficient separation of photogenerated carrier. Ti3+ sites adjacent to OVs promote N-2 chemisorption and activation through d-pi back-donation with the help of the unpaired d-orbital electron. Furthermore, a piezoelectric polarization field could modulate the electronic structure of Ti3+ to facilitate the activation and dissociation of N-2, thereby substantially reducing the reaction barrier of the rate-limiting step. Benefitting from the synergistic reinforcement mechanism and optimized surface dynamics processes, an exceptional piezo-photocatalytic NH3 evolution rate of 106.7 mu mol g(-1) h(-1) is delivered by BaTiO3 with moderate OVs, far surpassing that of previously reported piezocatalysts/piezo-photocatalysts. New perspectives are provided here for the rational design of an efficient piezo-photocatalytic system for the NRR.

Abstract ：
The construction of photothermal catalysts to provide advanced oxidation ability and stability is a great challenge for eliminating volatile organic compounds (VOCs) during the photothermal catalytic process. Herein, a bimetallic modification method was proposed to synthesize Pd/Fe-TiO2. Under ultraviolet-visible (UV-Vis) light irradiation with the intensity of 610 mW/cm(2), the optimal 0.7 wt% Pd/0.4 wt% Fe-TiO2 catalyst of which surface was detected at the temperature of 165 C can achieve a toluene conversion of 94 % and a CO2 yield of 87 %, respectively. Based on the results of in-situ DRIFTS, quasi-situ EPR, XPS, and O-2-TPD tests, it was found that two distinct types of Pd and Fe active sites not only generated reactive oxygen species (ROS) but also adsorbed toluene and intermediate species, which promoted the degradation of toluene. It is proposed that there be an electron transfer behavior between Fe and Pd nanoparticles, resulting in a synergistic interaction of the two metals. This study shows that creating bimetallic modification catalysts is an efficient method for eliminating VOCs through photothermal catalysis.

Abstract ：
Photocatalytic oxidative coupling of methane (POCM) is a direct way for the methane transformation into >= C2 alkanes. However, the typical oxygen activation path often leads to the formation of strong oxidizing superoxide radical (O-2(-)) species, which makes the whole reaction face serious selectivity problems. Herein, we constructed N and oxygen vacancy dual active sites on TiO2{001} nanosheets (TiO2-NVo) to regulate the oxygen activation pathway and achieve a high activity and selectivity of photocatalytic OCM. Compared with ordinary Au/TiO2{001} nanosheets, the alkane yields of Au/TiO2-NVo are increased from 16 mu mol h(-1) to 32 mu mol h(-1), and the selectivity of alkanes increased from 61% to 93%. The performance is superior when compared with the reported till date in photocatalytic OCM in batch reactors. The superior performance originates from the unique N-V-o dual active sites for synergistically cleaving the detrimental O-2(-) into desirable mono-oxygen active species (O-) to suppress undesired overoxidation reaction. The formed O- species from O-2(-) dissociation, in turn, is active for the selective H abstraction of CH4 into center dot CH3 to improve the subsequent C-C coupling reaction on the Au nanocluster surface. This work provides a new approach of O-2 dissociation to address the overoxidation of methane in an aerobic environment for achieving highly selective CH4 conversion.

Abstract ：
Photocatalytic hydrogen production from formic acid (FA) is a daunting challenge, yet an essential task forthe development of hydrogen energy. In this study, a p-NiO/n-TiO2 heterojunction incorporating 7-nm metallic Ni was fabricated, which demonstrated a remarkable localized surface plasmon resonance (LSPR) effect. Notably, 5 wt% Ni/TiO2 exhibited 1271 -fold higher photocatalytic activity (2416 mu mol center dot g- 1 center dot h-1) than TiO2 alone under light radiation at room temperature. The experimental investigations revealed the excitation of distinct components via irradiation by different light sources. Visible light -driven hydrogen production was predominantly influenced by the LSPR-induced hot electrons and holes effects of Ni. Further, FA molecules simultaneously lost and accepted electrons at the Ni0-Ti3+ and Ni0-O2- sites, respectively, generating a bidirectional electron transfer behavior with "valley -shaped" gas -sensitive responses, which was crucial to boost the activity. Moreover, the photocatalytic activity was mainly attributed to the heterojunction and defects structure under UV light irradiation, and Ti3+, VOs, and O2- as adsorption sites for FA. Thus, the synergistic interplay among different light sources could effectively boost the photocatalytic hydrogen production performance. Significantly, this research reveals that the LSPR effect of metallic Ni can effectively regulate electron transfer behavior and enhance visible light -driven photocatalytic activity.

Abstract ：
Pollution in water environments hinders both social progress and economic development. Wastewater treatment and the sustainable use of water resources are important factors in solving this problem. In a previous study, the authors proposed a process that used photocatalytic film as a back-end treatment in a composite iron-carbon constructed wetland (WIC&PF) to restore a mildly eutrophic water body. This method has strong reoxygenation effects, and can efficiently remove pollutants; these are qualities that have not been mentioned in previous studies regarding constructed wetlands. In this study, the authors further investigated the effectiveness of this process by using a photocatalytic film as a front-end treatment for a composite iron-carbon constructed wetland (PF&WIC) to restore a mildly eutrophic water body. The results showed NH4+-N, TN, TP, COD, and chlorophyll a removal rates using PF&WIC of 79.1 +/- 6.6%, 76.8 +/- 6.5%, 77.0 +/- 5.4%, 77.3 +/- 7.2%, and 91.7 +/- 5.6%, respectively. The DO concentration of the water body increased compared with that of the effluent. The bacterial species and their abundance in the lake water also changed significantly, and photosynthetic autotrophic bacteria (Cyanobium PCC-6307) became the most dominant bacteria, and this played an important role in reoxygenating the water body. In comparing these results to those of our previous study, the removal of pollutants with PF&WIC was close to that with WIC&PF, but the reoxygenation effect of PF&WIC on the water body was significantly worse than that of WIC & PF; thus, WIC&PF is the more reasonable choice for treating eutrophic water bodies.

Abstract ：
CO2 conversion with pure H2O into CH3OH and O-2 driven by solar energy can supply fuels and life-essential substances for extraterrestrial exploration. However, the effective production of CH3OH is significantly challenging. Here we report an organozinc complex/MoS2 heterostructure linked by well-defined zinc-sulfur covalent bonds derived by the structural deformation and intensive coupling of dx 2 - y2(Zn)-p(S) orbitals at the interface, resulting in distinctive charge transfer behaviors and excellent redox capabilities as revealed by experimental characterizations and firstprinciple calculations. The synthesis strategy is further generalized to more organometallic compounds, achieving various heterostructures for CO2 photoreduction. The optimal catalyst delivers a promising CH3OH yield of 2.57 mmol gcat-1 h(-1) and selectivity of more than 99.5%. The reverse water gas shift mechanism is identified for methanol formation. Meanwhile, energy-unfavorable adsorption of methanol on MoS2, where the photogenerated holes accumulate, ensures the selective oxidation of water over methanol.
