Abstract

PURPOSE: To uniformly disperse noble metal particles onto a carrier, by conjunctly using carbon powder as the carrier when a noble metal solution is mixed with a protective colloid and reacted with a reducing agent.
CONSTITUTION: To obtain a nobel metal catalyst, especially a catalyst suitable as an electrode in a fuel battery, a reducing agent, e.g., methanol, is mixed with water and a protective colloid, e.g., PVA, is dissolved in the mixture. To the mixed solution is added a noble metal ion or its complex salt, e.g., a chloroplatinic acid solution, and then carbon powder, e.g., acetylene black. Thereafter, the solution is heated and reacted, to obtain a platinum catalyst supported on the acetylene black. The protective colloid inhibits the coagulation of the noble metal particles, and improves their dispersion state. The carbon powder facilitates fine uniform dispersion of the noble metal particles.
