Abstract

Cu single atoms embedded in the C₃N₄ (Cu-SAs/C₃N₄) matrix exhibited high activity with 95% oxygenate selectivity for the direct conversion of methane at ambient temperature. The presence of abundant anchoring sites in C₃N₄ led to highly dispersed Cu–N₄ moieties, which were suggested to be the underlying active sites for methane conversion.
