What is Oxo Dicopper Anchored on Carbon Nitride for Selective Oxidation of Methane about?
## Abstract Selective conversion of methane (CH~4~) into value-added chemicals represents a grand challenge for the efficient utilization of rising hydrocarbon sources. We report here dimeric copper centers supported on graphitic carbon nitride (denoted as Cu~2~@C~3~N~4~) as advanced catalysts for CH~4~ partial oxidation. The copper-dimer catalysts demonstrate high selectivity for partial oxidation of methane under both thermo- and photocatalytic reaction conditions, with hydrogen peroxide (H~2~O~2~) and oxygen (O~2~) being used as the oxidizer, respectively. In particular, the photocatalytic oxidation of CH~4~ with O~2~ achieves >10% conversion, and >98% selectivity toward methyl oxygenates and a mass-specific activity of 1399.3 mmol g Cu^−1^h^−1^. Mechanistic studies reveal that the high reactivity of Cu~2~@C~3~N~4~ can be ascribed to symphonic mechanisms among the bridging oxygen, the two copper sites and the semiconducting C~3~N~4~ substrate, which do not only facilitate the heterolytic scission of C-H bond, but also promotes H~2~O~2~ and O~2~ activation in thermo- and photocatalysis, respectively.
