A series of unmodified bulk Al2O3 materials show an intrinsic activity for selectively catalyzing propane dehydrogenation. The Lewis acid site arising from the unsaturated Al-III site in the Al2O3 structure is the active site for the catalytic cycle. The gamma-Al2O3-200 catalyst shows the highest yield, which delivers an initial conversion of 48% and selectivity of 83%.
