<P>PROBLEM TO BE SOLVED: To avoid such an inconvenience that particle size cannot be optimized to a reaction system or a reactant due to the fact that the particle size of the metal particles constituting the catalyst becomes too small. <P>SOLUTION: The metal particles 4 having catalyst activity and an additive particles 3 for improving catalyst activity of the metal particles are precipitated and carried by a physical deposition, for example, sputtering on the surface of a conductive powder 2, and furthermore, are heated, that is, annealed simultaneously with, before or after the precipitation and carrying. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
