The oxidation of methane to formaldehyde on various Sn-Zr and Sn-Zr-Ce oxide catalysts have been investigated. The adsorption-desorption of n-butylamine and oxygen on the catalysts have been carried out by temperature programmed desorption method. The yield of formaldehyde was found to be correlative with Sn/Zr ratio and the amount of cerium in the catalysts. The activity of the catalyst in the formation of formaldehyde from methane was dependent upon the acidity of the catalyst and chemisorption states of oxygen. The results obtained from X-ray diffraction show that there is a strong influence of oxides of Sn in the catalyst on the activity.
