Supported Vanadium Catalysts for Selective Sulfur‐Oxidative Dehydrogenation of Propane

Abstract The catalytic oxidative dehydrogenation of propane (ODHP) is a challenging reaction due to facile competing overoxidation CO x . gaseous disulfur molecule, S 2 , isoelectronic with O and has been shown act as an alternative, “soft oxidant” for the analogous process (SODHP) over bulk metal sulfide catalysts. However, these catalysts suffer from low surface areas ill‐defined active sites – issues that might be addressed supported catalyst. Here we investigate V/Al 3 materials SODHP. We show are highly selective propylene, far surpassing yields prior systems. Isolated sulfided vanadium species found more than crystalline sulfide. Additionally, compare oxidants calcined materials, respectively, find propylene selectivity enhanced using oxidant. These results suggest sulfur promising soft oxidant can used achieve high selectivities sulfides.
