Abstract: Co-Pd bimetallic catalysts immobilized with four kinds of resins with different specific areas were prepared by means of the solvated metal atom impregnation (SMAI) method.The results of the XRD and the magnetic measurement showed that as the specific area of the resin increased,the particle sizes of Co and Pd on the catalysts with the same metal content decreased, so the catalytic activity of the catalysts for the hydrogenation of diacetone alcohol as well as the reduction of oxygen on the fuel cell electrode increased.Below 140 ℃, the conversion of diacetone alcohol increased as the reaction temperature increased, and above 140 ℃, the conversion decreased because of the rupture of the resin.

Key words: Cobalt-palladium catalyst, Diacetone alcohol hydrogenation, Fuel cell electrode
