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 ：
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 ：
Solar-driven methanation of carbon dioxide (CO2) with water (H2O) has emerged as an important strategy for achieving both carbon neutrality and fuel production. The selective methanation of CO2 was often hindered by the sluggish kinetics and the multiple competition of other C1 byproducts. To overcome this bottleneck, we utilized a biomass synthesis method to synthesize SiC rods and then constructed a direct Z-scheme heterojunction Co3O4/SiC catalyst. The substantial difference in work functions between SiC and Co3O4 served as a significant source of the charge driving force, facilitating the conversion of CO2 to CH4. The high-valent cobalt Co(IV) in Co3O4 acts as an active species to promote efficient dissociation of water. This favorable condition greatly enhanced the likelihood of a high concentration of electrons and protons around a single site on the catalyst surface for CO2 methanation. DFT calculation showed that the energy barrier of CO2 hydrogenation was significantly reduced at the Co3O4/SiC heterojunction interface, which changed the reaction pathway and completely converted the product from CO to CH4. The optimum CH4 evolution rate of Co3O4/SiC samples was 21.3 μmol g-1 h-1 with 100% selectivity. This study has an important guiding significance for the selective regulation of CO2 to CH4 products in photocatalysis applications. © 2024 American Chemical Society.

Abstract ：
The increasing environmental pollution and looming energy crisis necessitate the development of advanced photocatalysts that demonstrate efficient separation and transfer of the photo-generated holes and electrons, as well as multiple functions to address the above issues. Herein, a bifunctional Ni3S4/NiS2/v-Zn3In2S6 photocatalyst has been constructed to degrade environmental hormones and antibiotics with simultaneous H2 production. Sulfur vacancies have been engineered in the Zn3In2S6 from a kinetic point of view to accelerate the separation of photogenerated charge carriers and act as active sites. Ni3S4 and NiS2 are introduced to construct cascade electric fields with Zn3In2S6 via ohmic junctions for spatially separated charge carriers and reduced hydrogen evolution potential. As a result, the composite exhibits enhanced photocatalytic H2 production and efficient degradation of bisphenol A, norfloxacin, and tetracycline, respectively. Specifically, the degradation pathways of BPA have been investigated based on Fukui calculations and liquid chromatography-mass spectrometry techniques. This work may shed new light on the design and construction of dual-function photocatalysts for wastewater treatment and H2 production.

Abstract ：
Halogenated methane serves as a universal platform molecule for building high-value chemicals. Utilizing sodium chloride solution for photocatalytic methane chlorination presents an environmentally friendly method for methane conversion. However, competing reactions in gas-solid-liquid systems leads to low efficiency and selectivity in photocatalytic methane chlorination. Here, an in situ method is employed to fabricate a hydrophobic layer of TaOx species on the surface of NaTaO3. Through in-situ XPS and XANES spectra analysis, it is determined that TaOx is a coordination unsaturated species. The TaOx species transforms the surface properties from the inherent hydrophilicity of NaTaO3 to the hydrophobicity of TaOx/NaTaO3, which enhances the accessibility of CH4 for adsorption and activation, and thus promotes the methane chlorination reaction within the gas-liquid-solid three-phase system. The optimized TaOx/NaTaO3 photocatalyst has a good durability for multiple cycles of methane chlorination reactions, yielding CH3Cl at a rate of 233 mu mol g(-1) h(-1) with a selectivity of 83%. In contrast, pure NaTaO3 exhibits almost no activity toward CH3Cl formation, instead catalyzing the over-oxidation of CH4 into CO2. Notably, the activity of the optimized TaOx/NaTaO3 photocatalyst surpasses that of reported noble metal photocatalysts. This research offers an effective strategy for enhancing the selectivity of photocatalytic methane chlorination using inorganic chlorine ions.

Abstract ：
Photocatalytic selective oxidation of alcohols into aldehydes and H2 is a green strategy for obtaining both valueadded chemicals and clean energy. Herein, a dual-purpose ZnIn2S4@CdS photocatalyst was designed and constructed for efficient catalyzing benzyl alcohol (BA) into benzaldehyde (BAD) with coupled H2 evolution. To address the deep-rooted problems of pure CdS, such as high recombination of photogenerated carriers and severe photo-corrosion, while also preserving its superiority in H2 production, ZnIn2S4 with a suitable band structure and adequate oxidizing capability was chosen to match CdS by constructing a coupled reaction. As designed, the photoexcited holes (electrons) in the CdS (ZnIn2S4) were spatially separated and transferred to the ZnIn2S4 (CdS) by electrostatic pull from the built-in electric field, leading to expected BAD production (12.1 mmol g-1 h-1) at the ZnIn2S4 site and H2 generation (12.2 mmol g-1 h-1) at the CdS site. This composite photocatalyst also exhibited high photostability due to the reasonable hole transfer from CdS to ZnIn2S4. The experimental results suggest that the photocatalytic transform of BA into BAD on ZnIn2S4@CdS is via a carbon-centered radical mechanism. This work may extend the design of advanced photocatalysts for more chemicals by replacing H2 evolution with N2 fixation or CO2 reduction in the coupled reactions.

Abstract ：
Converting CO2 into hydrocarbons using solar energy enables the seamless integration of efficient solar energy utilization and carbon neutrality, presenting an efficacious solution to simultaneously tackle energy and environmental issues. However, challenges arise in controlling the selectivity of reduction products hinder its industrial application due to uncertainties in decisive factors. Given the complexity of the photocatalytic process, it is imperative to improve the understanding of the thermodynamic aspects (including consideration of both redox potential of photocatalysts and light absorption properties, activation of stable CO2 molecules, similarity in reduction potential of products) as well as kinetic obstacles (such as high adsorption potential, significant time disparity between charge separation and transfer, competition from side reactions). This Review offers a comprehensive analysis of the factors that govern product selectivity and explores effective strategies for enhancing catalytic performance based on recent advancements in photocatalytic CO2 reduction to diverse chemical compounds. These profound insights provide invaluable guidance for addressing challenges in practical applications of photocatalytic CO2 conversion.

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.
