Oxidative Dehydrogenation of Propane over Nanostructured Mesoporous VOx/CexZr1-xO2 Catalysts

High-surface-area mesoporous CexZr1-xO2 materials synthesized through a surfactant-assisted approach of nanocrystalline particle assembly are utilized as promising support for VOx-based catalysts. The catalytic properties the resultant VOx/CexZr1-xO2 nanocatalysts evaluated by oxidative dehydrogenation propane using microreactor-GC system. It is indicated that catalyst particles on nanoscale, having structure with uniform pore-size distribution and high surface area. behavior these nanostructured VOx/CexZr1-xO2 catalysts propane reaction relies vanadia loading amount, calcination temperature, area and Ce/Zr ratio supports, the size active compounds, additional contribution to propylene formation derives from propane under oxygen-lean conditions. catalyst prepared 8 wt% vanadia loading Ce0.2Zr0.8O2 exhibits high stable performance in propane reaction.&nbsp
