WebMar 15, 2024 · CO x may come from the oxidation of alkanes, olefins, and methyl in ODHP. Therefore, the oxidation reactions of propene, which is more reactive than ethylene, over the h-BN and VO x /γ-Al 2 O 3 catalysts were carried out. As shown in table S1, over-oxidation of propene readily occurs (about 99% CO x selectivity) on the VO x /γ-Al 2 O 3 catalyst.
