Abstract
Provided is a method for producing a catalyst for purification of exhaust gas, including the steps of: adding Zr ions to a solution containing a platinum hydroxide polymer; diluting the solution to which the Zr ions are added by using an aqueous ammonium acetate solution; immersing a support made of AlO, SiO, CeO, ZrO, or a composite oxide of any ones of these oxides in the diluted solution, followed by heating at 60 to 70° C., to thereby support the platinum hydroxide polymer on the support; and calcining the support, on which the platinum hydroxide polymer is supported, at 150 to 800° C.
