The CO2 oxidative dehydrogenation reaction (CO2 ODH) is a result of a two-step mechanism consisting of direct dehydrogenation followed by the reverse water-gas-shift (RWGS) that removes the hydrogen. Carbon deposits act as the selective catalyst of this reaction. For RWGS catalysis a metal function is required, but this increases deactivation.
