The catalytic performance and characterization of perovskitetype halo-oxide La1¡xSrxFeO3-δXσ (XDF, Cl) as well as La1-x SrxFeO3-δ(x=0-0.8) for the oxidative dehydrogenation of ethane (ODE) to ethene have been investigated. XRD results indicate that the catalysts had oxygen-deficient perovskite structures and TGA results demonstrated that the F-and Cl-doped perovskites were thermally stable. Under the reaction conditions of C2H6/O2/N2D 2/1/3.7, temperature=660℃C, and space velocityD6000 mL h¡1 g¡1, C2H6 conversion, C2H4 selectivity, and C2H4 yield were, respectively, 55.3, 45.1, and 24.9% over La0.6Sr0.4FeO3¡0.048; 76.8, 62.1, and 47.7% over La0.8Sr0.2FeO3¡0.103F0.216; and 84.4, 68.4, and 57.6% over La0.6Sr0.4FeO3¡0.103Cl0.164. Over the two halo-oxide catalysts, with an increase in space velocity, C2H6 conversion decreased, whereas C2H4 selectivity increased. Both La0.8Sr0.2FeO3-δ0.103F0.216 and La0.6Sr0.4FeO3-0.103Cl0.164 were durable within 40h of onstream ODE reaction. XPS results suggested that the presence of halide ions in the perovskite lattices promotes lattice oxygen mobility. It is apparent that the inclusion of For Cl-ions in La1¡xSrxFeO3-δ can reduce the deep oxidation of C2H4 and thus enhance C2H4 selectivity. Based on the results of O2-TPD and TPR studies, we suggest that the oxygen species that desorbed at temperatures ranging from 590 to 700℃ over the La0.8Sr0.2FeO3-0.103F0.216 and La0.6Sr0.4FeO3-0.103Cl0.164 catalysts are active for the selective oxidation of ethane to ethene.Byregulating the oxygen vacancy density and the oxidation states of B-site cations by implanting halide ions into oxygen vacancies in perovskite-type oxides (ABO3), one may obtain catalysts that are durable and selective for the ODE reaction.
