Doughnutlike structure CeNiO, prepared by a novel oxalate gel co-precipitation method, exhibited significantly higher activity in oxidative dehydrogenation (ODH) of propane at as 275 oC as low temperature than conventional catalysts such as VMgO. It is suggested that oxygen vacancy formed in CeO2 lattice due to the incorporating of Ni atoms adsorbs and activates the molecular oxygen to form active oxygen species. The superior performance for propane oxidative dehydrogenation over CeNiO catalyst is attributes not only to the properties of the CeNiO catalyst but also to its unique doughnutlike structure.

Keywords:Nickel; solid solution; propane ODH; oxygen vacancy
