Abstract The present invention relates to a complete oxidation catalyst for catalytic combustion treatment of industrial waste gas and autobobile tail gas. It contains Ag2O, La2O3, Mn2O3, SrO and gamma-Al2O3, its representation is Ag/La-Sr-Mn-O or Ag/La-Sr-Mn-O/gamma-Al2O3, and the mole percentages of all metal components is Ag 0.1-20.0 mol%, La 0.6-50.0 mol%, Mn 1.0-70.0 mol%, Sr 0.4-45.0 mol%, and Al 0-90.5 mol%. Said invented catalyst possesses high and stable catalytic activity,reaction depth and low working temp. for complete oxidation of low-concentration C1/C2 organic effluent, and the oxidation product is almost completely CO2, and other possible partial oxidation product, for example formaldehyde or acetaldehyde content is low to below the GC detection limit. Its catalyst preparation is simple, and its reproductibility is good.
