Abstract

In this research, Ag/C catalysts was respectively prepared by application of the polymeric complex protection for Ag(I) in different content of Ag. According to the characterizations by X-ray diffraction and scanning electron microscope, it was proved that the particle size of Ag , which was obtained by application of the polymeric complex protection for Ag(I), was related to the mass ratio of PVP and silver nitrate, the concentration of silver nitrate and sodium borohydride. Simultaneously the electrocatalytic activity of Ag/C catalysts is discussed through the polarization curves.
