PROCESS FOR PRODUCING CATALYST FOR DISCHARGE GAS TREATMENT

WIPO Patent Application WO/2006/095392

A1

A process for producing a catalyst for discharge gas treatment. It can reduce the amount of a noble metal to be deposited and thereby attains a reduction in production cost. The process, which is for producing a catalyst for the treatment of a discharge gas containing carbon monoxide and volatile organic compounds, comprises dissolving at least one metal salt to prepare an aqueous metal salt solution as a pH buffer, reducing the aqueous metal salt solution while keeping the pH constant to prepare a colloidal metal solution, and immersing a support in the colloidal metal solution to deposit the metal on the support. The amount of each metal thus deposited can be as small as 0.7 g/L or below.
