    • PURPOSE: Provided is a multifunctional oxidation catalysts, which can remove chlorinated volatile organic compounds at low temperatures of 20 to 220°C as well as minimize generation of another forms of chlorinated volatile organic compounds after reaction. CONSTITUTION: The present invention is characterized in that sulfated metal oxide support is impregnated with (i) as active species, 0.5-2.0 wt.% of one novel metal selected from Pt, Pd, Ir and Rh; (ii) as subsidiary active species, Cu 2.0-10.0 wt.%, Ni 0.1-1.0 wt.%. The sulfated metal oxide support is selected from zirconia, titania and ceria containing SO4 in an amount of 0.3 to 2.3 wt.%. And a porous molecular sieve material is used as support, together with the sulfated metal oxide support within the range of less than 50%. The porous molecular sieve material, such as protonic zeolite or ammonium zeolite, is selected from BEA, MFI, MOR and FAU zeolite with a Si/Al ratio within the range of 10 to 100.
