In Situ Integration of Metallic Catalytic Sites and Photosensitive Centers within Covalent Organic Frameworks for the Enhanced Photocatalytic Reduction of CO2

Covalent organic frameworks (COFs) are a promising platform for heterogeneous photocatalysis due to their stability and design diversity, but their potential is often restricted by unmanageable targeted excitation and charge transfer. Herein, a bimetallic COF integrating photosensitizers and catalytic sites is designed to facilitate locally ultrafast charge transfer, aiming to improve the photocatalytic reduction of CO
