Abstract: For oxidative coupling of methane(OCM)at 750℃, the C2selectivity and yield over SrF2/Nd2O3catalyst system were found to be obviously higher than those over Nd2O3.The in situ FTIR spectra were taken at OCM reaction temperature(700℃)and showed that O2-adspecies was observed on 50%SrF2/Nd2O3catalyst, which might be the active and C2selective oxygen species.

Key words: Oxidative coupling of methane, SrF2/Nd2O3, Oxygen adspecies
