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.

Abstract Photo-catalysis is a versatile method that used to remediate water pollution and other issues related the environment. Metal ferrite with spinel structure, which frequently as photocatalyst, another solution for remediation of environmental pollution. In this work, nanoparticles cobalt (CoFe 2 O 4 ) zinc oxide (ZnO) were prepared by sol-gel co-precipitation methods, respectively. CoFe /ZnO (CF/ZnO) its ternary nanocomposite CNTs (CF/ZnO@CNTs) fabricated wet-chemical approach. The materials characterized different characterization techniques, including X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR), UV–visible structural, functional group, optical study Band gap values calculated (CF, CF/ZnO, CF/ZnO) 2.45 eV, 3.37 2.18 Crystal violet phenol evaluation photocatalytic efficiency samples. case crystal degradation CF, ZnO CF/ZnO was 21.43 %, 46.43 66.62 Whereas, CF/ZnO@CNTs outperformed all catalysts 97.61 % dye. 53.70 83.33 exhibit excellent photodegradation activity than photocatalysts used. It because heterojunction fabrication presence they increase life span photo-generated species enhance surface area catalyst.
