Enhanced conversion of CO into CH on single atom Cu-anchored graphitic carbon nitride: Synergistic diatomic active sites interaction.

Single atom metal-nitrogen-carbon materials have emerged as remarkably potent catalysts, demonstrating unprecedented potential for the photo-driven reduction of CO. Herein, a unique Cu@g-CN catalyst obtained by cooperation of single atom Cu and nitrogen-rich g-CN is proposed. The particular CuN diatomic active sites (DAS) in Cu@g-CN contribute to the formation of highly stable CuOCN adsorption, a key configuration for CO activation and CC coupling.
