For oxidative coupling of methane(OCM)at 750℃, the C2 selectivity and yield over SrF2/Nd2O3 catalyst 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 adspecies was observed on 50%SrF2/Nd2O3catalyst, which might be the active and C2 selective oxygen species.
