Summary:A process for preparing the catalyst used to treat waste gas includes such technological steps as preparing catalyst milk, immersing foam ceramic in the catalyst milk until the pores of foam ceramic is full of the catalyst milk, centrifugal operation to remove excess milk, drying, calcine, immersing in solution of nitrate of noble metal, centrifugal operation to attach the catalyst monomer of noble metal, drying, calcine and reduction. The obtained catalyst has high purifying efficiency to waste gas.
