This study demonstrates enhanced propane conversion and propylene selectivity using Pd-B/Al2O3, indicating a shift from radical to surface-mediated mechanisms.
Boron-based catalysts typically promote the oxidative dehydrogenation of propane through a gas-phase radical mechanism, achieving high propylene selectivity but limited propane conversion. In this study, palladium is incorporated into B/Al 2 O 3 ...
