摘要：
LaF3 modified ZrO2, CeO2 and ThO2 catalysts for the oxidative coupling of methane indicate that ZrO2/LaF3, CeO2/LaF3 and ThO2/LaF3 Catalysts have high activity and high selectivity at low temperature. In the temperature region 480-650-degrees-C, the methane conversion is 24.38-30.8% and the C2= selectivity is 40-55.38%. The characterization of oxygen species on the catalysts indicates that, because of the modification of LaF3 to ZrO2, CeO2 and ThO2, it is favourable for the activation of O2.
