The oxidative dehydrogenation of ethane (ODE) and propane (ODP) to the corresponding alkene is one type of the important catalytic processes for the effective utilization of light alkanes. Compared to the commercial production for alkene via non-oxidative dehydrogenation, the ODE/ODP process is potentially advantageous because the reaction is exothermic. In this paper a series of ZrO2-doped NiO catalysts were prepared by a modified sol-gel method. XRD results show the lattice parameter increased with the rise in ZrO2 content. The B.E. of nickel and zirconium ion has a significant change due to electron transfer through bridge Zr-O-Ni interaction species. At lower temperature the higher propene/ethene yield is obtained on 16.7 wt% Zr-Ni-O catalyst with the higher selectivity. The weaker reducibility seems to be responsible enhanced alkene selectivity over Zr-Ni-O catalysts. Therefore, nanosized Zr-Ni-O catalyst is alternative for the alkene synthesis using a low-cost feedstock such as propane/ethane.
