XRD & XPS Study on the BaF2 Promoted Sm2O3-LaF3 Catalysts
摘要:
Sm2O3-LaF3 and BaF2 promoted Sm2O3-LaF3 catalysts shown good catalytic performance for the Oxidative Dehydrogenation of Ethane(ODE).XRD and XPS characterizations of the catalysts show the structure defects,which may be produced by the partial exchange of anions and cations,enhance the electron donating ability and increase the surface adsorbed oxygen concentration,thus should be favorable to improve the catalytic activity.However,the higher concentration of surface adsorbed oxygen is unfavorable for the ethene selectivity.
