Iron as an effective additive for enhancement of catalytic performance of cesium hydrogen salt of molybdophosphoric acid for selective oxidation of isobutane, propane, and ethane under oxygen-rich and -poor conditions and the catalyst design

The effects of iron addition and substitution on the catalytic performance of heteropoly compounds for selective oxidation were studied. The addition of iron to heteropoly compounds effectively enhanced the catalytic performance for the selective oxidation of light alkanes of ethane, propane, and isobutane under oxygen-rich and -poor conditions. Furthermore, on the basis of above results, it was attempted to synthesize mono-iron-substituted molybdophosphate, and a remarkable enhancement of catalytic performance was demonstrated for the oxidative dehydrogenation of 2-propanol.
