Understanding the origin of selective oxidative dehydrogenation of propane on boron-based catalysts

[Display omitted] •The supported B2O3/SiO2 catalysts show superior olefin selectivity in ODHP.•The surface oxidized boron species are the possible active sites for ODHP.•The >B--O-O--B< complex can act as a moderate oxidant to preferentially activate propane.•The suppressed adsorption of olefi...
