<P>PROBLEM TO BE SOLVED: To provide a production method for a catalyst by which a catalyst having high catalytic activity is obtained even if the production process therefor is simplified, and also produce a catalyst which has low cost with no damage in catalytic activity. <P>SOLUTION: The production method for the catalyst includes: an inverse micell preparation process 1 for preparing an inverse micell, which contains in it an aqueous solution containing at least a noble metal element as a catalytic active component, in an organic solvent; and a carrying process 2 for making a base material carry the catalytic active component to form a catalyst precursor; and a spray baking process 3 for adjusting a baking atmosphere and spray-bakes the catalyst precursor. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
