Low temperature selective oxidation of methane to methanol using titania supported gold palladium copper catalysts
The selective oxidation of methane to methanol has been studied using trimetallic AuPdCu/TiO 2 catalysts prepared by incipient wetness impregnation. They are able to catalyse the selective oxidation of methane to methanol under mild aqueous reaction conditions using H 2 O 2 as the oxidant. When comp...
