Abstract: The effects of B-site elements in LaMn1-yFeyO3 catalysts on the oxidation of CO and CH4 have been studied using temperature programmed desorption spectra measurements.Theactivity of the catalyst was related with both position and areas of oxygen desorption peakson the TPD curves.The active sites for CO and CH4 oxidation are not identical for thesame catalyst.CO was oxidized completely at 130℃ and CH4 at 300~500℃ over a ABO3-type catalyst of γ-Al2O3-supperted manganese system containing some additive oxides
