Schematic view of PODH reaction on CrOx doped CNT.
The catalytic activities of CeO2, ZrO2, (PH)-CeO2/ZrO2 and fluorite CeZrO4−δ oxides were reported for the oxidative dehydrogenation of ethyl benzene to styrene using O2, air and CO2 as oxidants. CeZrO4−δ accounted for a 47% styrene yield under optimized reaction conditions.
