Abstract  The oxidative coupling of methane (OCM) at low temperature was examined on Li- ZnO/La2O3 catalyst with w(Li)=2% and w(ZnO)=20%. CH4 conversion of 27.3% with C2 selectivity of 65.2% was obtained at 680 ℃ and the C2 yield reached 21.8% at 700 ℃ under reaction conditions. Raman and XPS results suggested that the low- temperature activity was related to the concentration of adsorbed oxygen species on the catalyst surface and La2O2CO3 was supposed to be responsible for the enhancement of C2 selectivity in OCM.
