In the presence of surface OH, exposure of CH_4 caused the production of RCO species on MgO, while olefinic species was mainly produced on La-doped MgO. In the case of CH_4-pretreated surface, ammonia formed NCO species on MgO, not on La-doped MgO. We conclude that the higher selectivity of C_2 compounds in oxidative coupling of methane on La-doped MgO is ascribed to La's inhibition effect on breaking olefinic C-C bond produced from CH_4 ; this breaking forms RCO species leading to CO_x species.}, pages = {13--21}, title = {Modification Effect of La on the Adsorption Behavior of CH_4 on MgO}, volume = {25}, year = {1993} }
