Catalytic studies over a series of WO_x–VO_x catalysts supported on porous silica, combined with DFT calculations demonstrated that propane dehydrogenation in the presence of CO₂ can proceed simultaneously via direct oxidative dehydrogenation and non-oxidative dehydrogenation followed by the reverse water gas shift reaction over. v The activation of the secondary C-H bond of propane is rate-limiting, while re-oxidation of the catalyst with CO₂ is potentially much faster.
