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 ：
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 ：
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 ：
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.

Abstract ：
A prepared p -type PdO/n-type TiO2 junction was prepared as the catalyst for photocatalytic hydrogen evolution from formic acid (FA). It was found that PdO/TiO2 exhibited 1298 -fold higher activity than TiO2 under ultraviolet and visible light irradiation at room temperature. Multiple characterization techniques were utilized to demonstrate that doping PdO into TiO2 can regulate the Fermi level of the sample and the adsorption behavior of FA, resulting in different electron transfer behavior between FA and PdO/TiO2 compared to that between FA and TiO2. Oxygen vacancies acted as electron donors to deliver photogenerated electrons from TiO2 to the adsorbed bidentate FA, which increased the electron density on the O atom of FA and led to the formation of activated monodentate FA. This activated FA was more easily oxidized by the holes in PdO generated by visible light, leading to the production of H2 and CO2. The mode of adsorption associated with the Pd2+ site is the key factor in driving this reaction and leading to the reversible electron transfer phenomenon. This study provides a new promising route for the design of photocatalysts for self -decomposition reactions.

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 ：
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 ：
Membrane distillation technology, utilized for treating hypersaline wastewater from seawater desalination, often encounters challenges related to inorganic scaling, adversely affecting membrane performance. Herein, we introduce a innovative approach employing a sacrificial layer on the surface of Thin Film Composite (TFC) membranes to concurrently enhance inorganic scaling resistance and facilitate membrane reusability. The sacrificial layer (Fe3+-TA) 3 +-TA) consisted of tannic acid (TA) complexed with iron ions (Fe3+) 3 + ) and could be removed and regenerated in situ. The results demonstrated that the Fe3+-TA 3 +-TA layer significantly improved the membrane's surface smoothness and densification, maintaining superior anti-scaling performance. The modified membrane exhibited remarkable durability, sustaining six reuse cycles with a flux recovery exceeding 97 % in gypsum scaling tests. Furthermore, the formation of new complexes during gypsum scaling tests confirmed the membrane's augmented scaling retardation capabilities. Thus, integrating of a sacrificial layer into TFC membranes presents a promising strategy for advancing membrane distillation processes in hypersaline wastewater treatment.

Abstract ：
The progressive transfer of photogenerated electrons between the catalyst components and reactants is of great significance for photocatalysis. Amorphous Pd (PdA) and oxygen vacancies (VOs) were simultaneously introduced in Pd-In2O3 exploiting hydrogen-induced amorphization effects; 0.6 wt% Pd-In2O3 exhibited a 4.5-fold increase in activity and a 3.2-fold higher selectivity toward CH3OH + CO (63.62 %) compared with In2O3. Multiple in situ techniques and theoretical calculations revealed that intercomponent electron transfer channels were established via various interface structures formed between PdA or crystalline Pd (PdC) and In2O3; PdA acted as electronic pump, facilitating the transfer and separation of photogenerated electrons, resulting in their subsequent enrichment on the surface of PdA. Simultaneously, PdA acted as electron-donating adsorption site for H2O, increasing the number of electrons received by H2O, further inhibiting the competitive adsorption of H2O and CO2 on VO sites, and promoting the hydrogen evolution reaction. Additionally, the electronic coupling between PdC and VOs could significantly decrease the electron-donating ability of VOs, reducing the number of electrons received by CO2, thus effectively regulating the degree of CO2 reduction. This study employs PdA/PdC and VOs to synergistic optimize the progressive transfer of photogenerated electrons, and presents a novel approach for elucidating the catalytic mechanism.
