Regulating the Ligand N-Heterocyclic Coordination in Bismuth-Based MOFs for Efficient CO Photoreduction.

The increasing global concern over environmental degradation and resource depletion has driven the search for sustainable technologies to mitigate CO emissions. Recently, bismuth-based metal organic frameworks (Bi-MOFs) have garnered significant attention due to their high stability, adjustable porosity, and excellent light absorption properties. However, weak visible light absorption and charge recombination are still obstacles to wide application.

Ether-Embedded Covalent Organic Frameworks Enable Efficient Photocatalytic CO Reduction.

The photocatalytic conversion of carbon dioxide (CO) into valuable solar fuels is a promising strategy for addressing energy crises and mitigating the greenhouse effect. However, the challenge of efficiently regulating photogenerated electrons to CO active sites remains a key hurdle for high-performance CO reduction. Herein, an embedded functional group, ether group is introduced into porphyrin-triazine COFs to regulate the transfer behavior of photogenerated electrons.
