Nanosized CeNbNiO catalysts have been prepared by a modified sol–gel method and investigated in the oxidative dehydrogenation of propane to propene (ODHP). The addition of Nb into NiO can enhance the propene selectivity, while Ce introduction can largely increase propane conversion at low temperature. With 1.5Ce3NbNiO catalyst, a propene yield of 10.4% was obtained at 250 °C. XRD, N2-adsorption, H...
Mesoporous nickel oxide was prepared using sodium dodecyl sulfate as the template and urea as the hydrolysis agent. The method was extended successfully to the synthesis of a mesoporous multicomponent Ni-based catalyst, NiMgO. The mesostructured catalysts were compared with a nanosized NiO catalyst prepared by a sol-gel process. These catalysts were used for oxidative dehydrogenation of ethane to...
