Synergistic photocatalysis–Fenton reaction for selective conversion of methane to methanol at room temperature

Abstract

By combining the Fenton and photocatalytic reactions, the selective conversion of CH₄ to CH₃OH on TiO₂ was significantly enhanced with solar light at room temperature. The yield and selectivity to methanol are up to 471 μmol g⁻¹ h⁻¹ and 83%, respectively. The Fenton reaction favors the generation of radicals. Photocatalysis facilitates the closed cycle of catalysis and Fenton reagent restoration.
