Abstract
This paper presents a novel photon-phonon-driven cascade reaction for converting methane to formaldehyde with high productivity (401.5 µmol h⁻¹) and selectivity (90.4%) at 150 °C. A ZnO catalyst decorated with single Ru atoms facilitates a two-step process: photocatalytic production of methyl hydroperoxide followed by its thermodecomposition into formaldehyde. Single Ru atoms enhance charge separation and oxygen reduction, leading to improved efficiency and minimizing energy consumption.
