<P>PROBLEM TO BE SOLVED: To provide a method of synthesizing catalyst fine particles by highly dispersing them and, for more detail, to provide a technique of increasing dispersion property of catalyst ink, catalyst ink prepared by using it, and a catalyst electrode. <P>SOLUTION: Carbon fine particles hardly dispersing in a polar solvent and sulfonate group-introduced amorphous carbon easily dispersing in a polar solvent are mixed with each other, and both of them are subjected to π-π stacking bonding. A metal salt or metal colloid are added in the solution with the mixture of the sulfonate group-introduced amorphous carbon and the carbon fine particles dispersed therein, and a reducing agent is added thereto while agitating them. <P>COPYRIGHT: (C)2009,JPO&INPIT |
