<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an exhaust gas treating catalyst, by which the amount of a noble metal to be deposited is made small so that the manufacturing cost of the exhaust gas treating catalyst can be reduced. <P>SOLUTION: This method for manufacturing the catalyst for treating exhaust gas containing carbon monoxide and a volatile organic compound comprises the steps of: preparing a metal salt aqueous solution as a pH buffer solution, in which at least one metal salt is dissolved; preparing a metal colloidal solution by reducing the metal salt aqueous solution while keeping the pH of the metal salt aqueous solution constant; immersing a carrier in the colloidal solution so that a metal is deposited on the carrier. According to this method, the amount of one metal to be deposited on the carrier can be made to be ≤0.7 g/L. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
