The oxidative dehydrogenation of propane (ODHP) as a method of “on-purpose” propylene production has been broadly studied as an alternative to cracking and dehydrogenation.1 However, even after decades of research establishing supported vanadium oxide as the state-of-the-art catalyst for ODHP,2,3 selectivity to the olefin product remains too low to be commercially attractive because of facile over-oxidation of propylene into CO and CO2 (COx). During this presentation I will bring the story of how we discovered that boron and boron containing materials (like BN, B4C, NiB, amongst others) are highly selective catalysts for the ODHP reaction.6,7 Kinetic and spectroscopic insights will be combined to shine light on potential reaction mechanisms.8,9 FTIR, Raman, XPS, XAS and MAS NMR spectroscopy all indicate that the surface of all tested boron-containing materials becomes partially oxidized, forming an active layer of BOxHy species. The reactivity of this surface layer is likely influenced by the properties of the bulk material, opening new possibilities for future catalyst development.
