Abstract:
Photocatalytic reduction of CO 2 with H 2 O is thought as an environment friendly approach for sustainable development. It is highly desirable but remains challenging to develop photocatalyst with metal -free site for CO 2 reduction. Here, we fabricated a heterostructure by integrating azine-based COF with ZnIn 2 S 4 , where the azine unit in COF acts as metal -free sites for CO 2 adsorption and reduction. The as -formed interfused heterointerface in the heterostructure ensures the effective electron transfer from ZnIn 2 S 4 across the interface to the COF, resulting in a spatial separation of redox sites for CO 2 reduction and water oxidation. The hybrid catalyst exhibits remarkably enhanced photocatalytic activity for CO 2 reduction to CO, which is 8 and 6 times than the COF and ZnIn 2 S 4 , respectively, and is even comparable with some metal -catalyzed CO 2 reduction systems. This study provides a new paradigm to mimic natural photosynthesis by using metal -free site for CO 2 reduction. (c) 2024, Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
