Direct functionalization of methane into ethanol over copper modified polymeric carbon nitride via photocatalysis.

ABSTRACT: Direct valorization of methane to its alcohol derivative remains a great challenge. Photocatalysis arises as a promising green strategy which could exploit hydroxyl radical (·OH) to accomplish methane activation. However, both the excessive ·OH from direct H₂O oxidation and the neglect of methane activation on the material would cause deep mineralization. Here we introduce Cu species into polymeric carbon nitride (PCN), accomplishing photocatalytic anaerobic methane conversion for the first time with an ethanol productivity of 106 μmol g_cat^-1 h^-1. Cu modified PCN could manage generation and in situ decomposition of H₂O₂ to produce ·OH, of which Cu species are also active sites for methane adsorption and activation. These fea
