Comparatively high CH₃OH selectivity (60.0%) and yield (6.7%) were obtained on MoO_x/(LaCoO₃+Co₃O₄) catalysts in selective oxidation of methane to methanol using molecular oxygen as oxidant. The interaction between MoO_x and La-Co-oxide modified the molecular structure of molybdenum oxide and the ratio of O^-/O^2- on the catalyst surface, which controlled the catalytic performance of MoO_x/(LaCoO₃+Co₃O₄) catalysts.
