Summary: A highly active and stable NiO nanocrystalline decorated on ZnO-CoNi solid solution catalyst is reported, which achieves 88% photocatalytic conversion of methane to CO2 and H2O under ambient conditions. The excellent performance of the catalyst originates from the high mobility of surface lattice oxygen of supported NiO nanocrystallines driven by the photogenerated electrons and internal electric field of ZnO-CoNi solid solution. Moreover, even at high methane concentrations up to 5000 ppm, the methane conversion of the catalyst remains above 37%, showing promise for methane elimination applications near large methane emission sources.
