Abstract Carbon recycling is poised to emerge as a prominent trend for mitigating severe climate change and meeting the rising demand energy. Converting carbon dioxide (CO 2 ) into green energy valuable feedstocks through photocatalytic CO reduction (PCCR) offers promising solution global warming needs. Among all semiconductors, zinc oxide (ZnO) has garnered considerable interest due its ecofriendly nature, biocompatibility, abundance, exceptional semiconducting optical properties, cost‐effectiveness, easy synthesis, durability. This review thoroughly discusses recent advances in mechanistic insights, fundamental principles, experimental parameters, modulation of ZnO catalysts direct PCCR C 1 products (methanol). Various modification techniques are explored, including atomic size regulation, synthesis strategies, morphology manipulation, doping with cocatalysts, defect engineering, incorporation plasmonic metals, single atom boost performance. Additionally, highlights importance photoreactor design, reactor types, geometries, operating modes, phases. Future research endeavors should prioritize development cost‐effective catalyst immobilization methods solid‐liquid separation recycling, while emphasizing use abundant non‐toxic materials ensure environmental sustainability economic viability. Finally, outlines key challenges proposes novel directions further enhancing ZnO‐based conversion processes.

The generation of hydrogen through photocatalysis is a fascinating technology for addressing environmental concerns and the energy crisis. Nevertheless, quest cost-effective, stable, efficient photocatalysts in realm conversion remains significant challenge. Herein, we designed novel InVO4/Ti3C2 MXene (IVTC) heterostructures by employing acid etching to produce Ti3C2 with an accordion-like morphology, using hydrothermal technique production orthorhombic InVO4 nanoparticles (NPs), integrating them self-assembly approach. Both field-emission scanning electron microscopy HRTEM analyses revealed consistent distribution NPs average size 43.4 nm on both surfaces between sheets MXene. intimate interface nanosheet suppressed carrier recombination promoted charge transfer, thereby boosting photocatalytic H2 production. Under visible light exposure, rate evolution enhanced IVTC containing optimized 10% loading InVO4, exhibiting over 3-fold increase compared pristine NPs, maintaining efficiency across four cycles. This research presents promising method designing creating high-efficiency possessing excellent visible-light-driven activity evolution.

In this study, we developed a solid-state atomic replacement method for metal catalysts, enabling the exchange of atoms between single and nanoalloys to create new combinations atoms. We observed that partial interchange occurred RuNi nanoalloy Zn from zeolitic imidazolate framework-8 (ZIF-8) on carbon–nitrogen framework (CNF) at high temperature 900 °C, leading creation RuZn nanoparticles nickel (Ni-CN). Extended X-ray absorption fine structure (EXAFS) near edge (XANES) analyses revealed Ni is atomically dispersed within (RuZn)/Ni-CN. This finding confirms migration during pyrolysis RuNi@ZIF-8 precursor, providing definitive evidence replacement. Due synergistic influence nanocrystals Ni-CN, resulting (RuZn)/Ni-CN multisite catalyst exhibited superior hydrogen evolution reaction (HER) ability compared conventional nanoalloy-based catalysts. Density functional theory calculations integration (RuZn)n cluster surrounded with different N-coordinated carbon structures enhanced HER activity optimized (RuZn)n/NiN2C2 exhibiting low ΔGH improved electron charge redistribution, thereby promoting favorable adsorption. Our findings provide valuable insights into design optimization photocatalysts through atomic-level engineering, opening avenues efficient sustainable energy conversion technologies.
