“…Subsequently, reduction or activation procedures are carried out to form Ir-based catalysts with atomically dispersed Ir species. These steps are crucial in achieving the desired dispersion and isolation of individual Ir atoms on the substrate, enabling the synthesis of highly efficient catalysts with unique properties and reactivity (Pham et al, 2023).…”

Photoreduction of CO2 into hydrocarbon fuels is a promising avenue for achieving a sustainable alternative to the artificial carbon cycle. Photocatalytic CO2 conversion is the chemical transformation of photogenerated carriers and adsorbed CO2 at active sites of catalysts. Active sites can regulate the kinetic process of carriers, control the adsorption of CO2 and intermediates, lower activation barriers, and promote C‐C coupling. This review mainly concentrates on the efficiency and selectivity regulation of the target products through construction of active sites. First, the principles of CO2 photoreduction, such as the influencing factors and specific pathways for monocarbon and multicarbon (C2+) formation, are discussed. Then, leading works focusing on improving catalytic efficiency and regulating product selectivity through the introduction of active sites are highlighted, concerning the underlying mechanism of the performance, especially for C2+ generation. Subsequently, an overview of the currently available in situ techniques and theoretical calculation for identifying the active sites are provided. Finally, the challenges of emerging strategies to achieve carbon recycling from scientific, technical, and economic perspectives are considered. This review offers deep insight into the construction of active site with atomic precision to achieve efficient photocatalytic CO2 conversion and the generation of C2+ in high selectivity.

With increasing energy demands and environmental issues, renewable energy‐related conversion systems have gained significant attention as a potential substitute for traditional fossil fuel‐based energy technologies. First introduced by S.W.Grove in 1838, fuel cells have been extensively developed into many different types, and direct alcohol fuel cells (DAFCs) are of interest as a potential power source because of their large power density, quick start, simplicity, and nearly zero emission. However, the high cost and poor catalytic efficiency of current catalysts are primary barriers to commercializing DAFCs. Designing advanced nanocatalysts for both anode and cathode electrodes is of crucial importance for practical DAFC development; however, a brief evaluation of current progress in electrocatalyst development for the alcohol oxidation reaction (AOR) and oxygen reduction reaction (ORR) is still very little. Herein, recent advances in fuel cell catalysts, mainly focusing on several most active areas (i.e., Pt‐ and Pt‐free‐based catalysts, metal‐free carbon, carbon‐based nonprecious metal composites) are concisely summarized. Also, challenges and prospects for DAFCs are highlighted to supply a comprehensive view for further designing high‐performance DAFC catalysts.
