PURPOSE: Provided is a refractory inorganic oxides catalyst supported by solid powder with enhanced activity and selectivity, exhibiting no inactivation after the use of 200 hours. The catalyst is used in PROX reaction, elimination of volatile organic material and catalytic oxidation. CONSTITUTION: The treatment method comprises the steps of making inorganic organic catalyst such as alumina, titania and silica oxide by slurry washing to the honeycomb, drying, calcining at 300-800deg.C and cooling to 100deg.C; and improving the surface of the above catalyst by heating at more than 100deg.C and flowing on its surface with one or more liquid materials selected from water, alcohols, ammonia water, hydrogen peroxide water and hydrochloride and with one or more gases chosen from hydrogen, oxygen, ozone, carbon monoxide, methane, propane and butane.
