Defect-promoted visible light-driven CC coupling reactions pairing with CO2 reduction
Pairing CO 2 reduction with oxidative organic synthesis in one photoredox cycle opens a new avenue for cooperative utilization of excited electrons and holes towards efficient solar-to-chemical energy conversion. In this work, we demonstrate a facile cetyltrimethylammonium bromide (CTAB) surfactant functionalized ZnIn 2 S 4 (ZIS)-based dual-functional reaction system for efficient visible light-driven CO 2 -to-CO conversion pairing with selective oxidation of benzyl alcohol to value-added C C coupled products. Our research suggests that the markedly enhanced redox activities are mainly attributed to the unique structure of CTAB-ZIS featuring more crystalline and surface defects, which greatly promotes the interfacial charge carrier transfer, and in particular elevates CO 2 activation and electrons reducibility. It is anticipated that this work would inspire further establishment of efficient novel photocatalysts and cooperative reaction system coupling CO 2 reduction and organic synthesis in a cost-effective manner under ambient conditions to meet the economic and social sustainability goals.
