Abstract
The present invention relates to a method for preparing catalyst platinum supported on lithium cobalt oxide for sodium borohydride hydrolysis. The catalyst with crystalline platinum is produced by mixing dihydrogen hexachloroplatinumate and black lithium-cobalt-oxide powder with the impregnation method, and then by a two-step sintering. Platinum is the major catalytic activity site, and lithium cobalt oxide is the support thereof. The manufacturing process of the present invention is simple, and can be applied to catalytic reactions or electrocatalytic reactions in fuel cells. Thereby, the present method is very practical to industry.
