Abstract
- Defect-promoted dual-functional reaction system : a cetyltrimethylammonium bromide (CTAB) functionalized ZnIn 2 S 4 (defectived ZIS)-based dual-functional reaction system enables efficient visible light-driven CO 2 -to-CO conversion and simultaneous selective oxidation of benzyl alcohol (BA) to C C coupled products in a cooperative photoredox manner. • A dual-functional reaction pairing CO 2 reduction and oxidative organic synthesis. • Structure distorted CTAB-ZIS fabricated by a CTAB assisted hydrothermal process. • Defect structure of CTAB-ZIS favors oxidation of BA to C C coupled products. 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.
