Published: July 23, 2024

Abstract Atomically dispersed active sites in a photocatalyst offer unique advantages such as locally tuned electronic structures, quantum size effects, and maximum utilization of atomic species. Among these, asymmetric dual‐sites are particular interest because their charge distribution generates local built‐in electric potential to enhance separation transfer. Moreover, the dual provide flexibility for tuning complex multielectron multireaction pathways, CO 2 reduction reactions. The coordination opens new possibilities engineering structure–activity–selectivity relationship. This comprehensive overview discusses efficient sustainable photocatalysis processes photocatalytic reduction, focusing on strategic active‐site design future challenges. It serves timely reference development conversion processes, specifically exploring here exemplified by into valuable chemicals.
