Abstract:Sulfur vapor (S2) is an effective alternative
oxidant
for propane dehydrogenation, (S)ODHP, with vanadium-based catalysts
displaying promising performance and propylene selectivity significantly
greater than with O2 as the oxidant (ODHP). However, a
deeper mechanistic understanding of SODHP versus ODHP will be necessary
for further catalytic performance. Here, we investigate these trends
over vanadium catalysts supported by Al2O3,
TiO2, ZrO2, and SiO2. First, support
