Selective Oxidation of Ethane, Propane, and Isobutane Catalyzed by Copper-Containing Cs2.5H1.5PVMo11O40under Oxygen-Poor Conditions☆

Abstract Effects of the addition of various transition metal additives to Cs 2.5 H 1.5 PVMo 11 O 40 on the catalytic performance for oxidation of ethane were compared under oxygen-poor conditions and copper was found to most enhance the catalytic performance. Similar enhancements by the addition of copper were observed for the oxidation of propane and isobutane under oxygen-poor conditions. It is suggested that the enhancement by the copper addition is due to the promotion of the reoxidation of the catalyst.
