Small, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 4, 2024

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.
