Producing propene by the oxidative dehydrogenation of propane (ODH) has become an attractive and feasible route for bridging production-demand gap, either as a complementary existing oil-based processes or new alternative from separated natural gas. The industrial application ODH not succeeded so far due to low yields. Therefore, been extensively investigated in recent decades using different catalysts reaction conditions. Although several important aspects have discussed previous reviews (e.g., supported vanadium oxide catalysts, bulk productivity toward propene, etc.), other relevant addressed support effects, loading vanadia precursor catalyst synthesis methods, surface impurities, structure–reactivity relationships, etc.). In this review, we endeavor cover majority publications with emphasis on following: (1) synthesis: focus influence methods final species, (2) characterization: identify molecular structures species well physical chemical characteristics, (3) kinetics: understand how rates depend variables such concentration gas-phase reactants temperature, (4) structure–activity relationship: examine kinetics, (5) mechanism: use relationships kinetic studies plus theoretical calculations corroborate and/or propose pathways that account overall ODP mechanism.
