| Abstract: | In this paper, the catalytic activity of semiconductor metal oxides for propane oxidative dehydrogenation was investigated. It was found that p\|type semiconductor metal oxides showed low temperature catalytic properties and n\|type ones revealed high temperature catalytic behaviors. H\-2\|TPR, O\-2\|TPD\|MS and in situ electrical conductivity studies confirmed that the active oxygen species of p\|type semiconductor catalysts were nonstoichiometric oxygen species and the ones of n\|type catalysts were surface lattice oxygen. |
| Keywords: | Propane Oxidative dehydrogenation Oxide catalyst Active oxygen species |
