Abstract

AbstractAt atmospheric pressure, the main challenge in the photocatalytic oxidation of CH4 to CH3OH is to absorb and activate the inert C─H bond while preventing excessive oxidation of CH3OH. In this study, metal‐supported ZnO nanoflowers (Ag‐ZnO) are designed to produce abundant active interfacial oxygen sites for CH4 oxidation at atmospheric pressure, with a CH3OH yield reaching 1300 µmol gcat
