ABSTRACT:
A method for producing a catalyst of the present invention is characterized by sequentially performing the steps of: (i) dipping an end face portion of a carrier structure having a catalytic component carried thereon in an aqueous metal salt solution at a concentration of 2.7 to 3.88 mol/L in terms of mole of the metal; (ii) drying the dipped end face portion; (iii) dipping the dried end face portion again in an aqueous metal salt solution whose metal species is the same as that in the aqueous metal salt solution at a concentration of 2.7 to 3.88 mol/L in terms of mole of the metal; and (iv) performing a calcination treatment to harden the catalytic end face.
