The direct photocatalytic oxidation of methane to value-added chemicals has garnered considerable interest in recent years. However, achieving high productivity while maintaining selectivity at an appreciable conversion rate remains a formidable challenge. Here, we present photochemically-triggered and photothermally-enhanced oxidative coupling multi-carbon C2+ alkanes over Au CeO2 nanoparticle-decorated ZnO photocatalyst, which exhibits record-breaking production 17,260 μmol g−1 h−1 with ~90% under wide-spectrum light irradiation without secondary source heating. Comprehensive characterizations computational studies reveal that CH4 activation is photochemical reaction initiated by ultraviolet light-excited ZnO, the introduction substantially enhances O2 due cooperative interaction between CeO2. Concurrently, nanoparticles capture visible near-infrared generate localized heating, greatly promotes subsequent desorption produced methyl radical for C–C prior undergoing further undesired overoxidation. Achieving both activity photooxidation hydrocarbons challenging. This work shows integrating photothermal effects both, enabling efficient alkanes.
