Nanometer oxide LaMnO_3+λ and its counterparts with large particle size were comparatively studied for total oxidation of methane.XPS, TPR and nonstoichiometric oxygen(λ) analysis results identify that the nanometer oxide contains more high valence cations, to which the adjacent lattice oxygen are responsible for total oxidation of methane at low temperature.
