“…This band overlaps bands 2940-2930 cm -1 which are assigned to asymmetric methyl (ν as CH 3 ) and methene (ν as CH 2 ) stretching, and bands around 2860 cm -1 assigned to symmetric methyl (ν s CH 3 ) and methene (ν s CH 2 ) stretching [15,53,54]. Bands at lower wavenumbers; 1473 and 1388 cm -1 could be attributed to asymmetric methyl (δ as CH 3 ) and symmetric methyl (δ s CH 3 ), respectively.…”

“…ODH has the advantage of an exothermic reaction without thermodynamic limitations and with a low risk of catalyst deactivation through coking because the reaction is performed in an oxidative environment. A wide variety of catalytic systems has been proposed for this reaction, the most studied of which are based on V516 or Mo 17–25. Though scarcely studied, other transition‐metal‐based catalytic materials could exhibit comparable catalytic efficiencies 2636.…”

“…4 and Fig. 5 that the vanadium loading promotes the adsorption of propane on γAl 2 O 3 , and V=O, V−O‐Al and V−O‐V are active sites for adsorbing propane, resulting in the formation of carbon dioxide . Therefore, it can be concluded that the adsorption of propane occurs at a low temperature, and the V‐γAl 2 O 3 catalyst catalyzes the formation of propylene by propane at 500 °C.…”
