The solvated metal atom impregnation (SMAI) method was employed to prepare Ni Ag bimetallic catalysts immobilized with four kinds of resin of different specific area. The results of XRD and magnetic measurement showed that as the specific area of the resin increased, the particle size of Ni and Ag on the catalysts with the same metal content decreased, so the catalytic activity of the catalysts in hydrogenation of toluene and diacetone alcohol as well as in reduction of oxygen on the fuel cell electrode increased.
