Abstract
Photocatalytic CO₂ reduction to ethylene/ethane offers a sustainable and cost-effective approach to simultaneously produce these high-demand chemicals while reducing atmospheric CO₂ level. Lately, atomic active centers (AACs) anchored photocatalysts are comprehensively investigated for their exceptional photocatalytic performance regarding the photosynthesis of ethylene/ethane. This review provides a critical summary of the incorporation of various AACs, such as Cu, Au, Ag, Mo, Ni, P/Cu, and CuAu, onto different photocatalyst supports, including metal oxide, carbon nitride, red phosphorous, covaleng organic framework , and bimetallic sulfide together with their crucial role in raising the rates of ethylene/ethane production and selectivities. Furthermore, this review offers a comprehensive summary/analyses of preparation routes, chemical composition, atomic configurations, coordination structures, optical characteristics, structure–performance relationship, reaction intermediates, reaction pathways, photocatalysis mechanism, and photocatalytic performances of the as-prepared AAC anchored photocatalysts using state-of-art in situ characterization techniques. This review also emphasizes the challenges in the process of photocatalytic CO₂ conversion to target products, the role of anchored AACs, limitations, potential applications, and future outlooks for AACs anchored photocatalysts.
