| description | Photocatalytic reduction of CO2 to useful fuel has been identified as a promising strategy to address the energy and environmental issues. Development of well-defined photocatalysts toward CO2 reduction has attracted increasing interest to gain insight into the reactive mechanism. Herein, by post-synthetic ligand exchange, a bifunctional Re-based metal–organic framework (MOF) was successfully prepared. It not only serves as a photosensitizer but also acts as a catalyst for photochemical reduction of CO2. Furthermore, it is found that a Re-based MOF containing 30% Re-based ligands displays improved activity compared to MOF with 100% Re-based ligands. This work provides clues to the design and synthesis of bifunctional MOFs toward photocatalytic CO2 reduction. |
