Selective light-driven methane oxidation to ethanol.

ABSTRACT: Methane (CH₄) photocatalytic upgrading to value-added chemicals, especially C₂ products, is significant yet challenging due to sluggish energy/mass transfer and insufficient chemical driven-force in single photochemical process. Herein, we realize solar-driven CH₄ oxidation to ethanol (C₂H₅OH) on crystalline carbon nitride (CCN) modified with Cu₉S₅ and Cu single atoms (Cu₉S₅/Cu-CCN). The integration of photothermal effect and photocatalysis overcomes CH₄-to-C₂H₅OH conversion bottlenecks, with Cu₉S₅ as a hotspot to convert solar-energy to heat. In-situ characterizations demonstrate that Cu single atoms play as electron acceptor for O₂
