Abstract

Pt-Ni-Au nano catalysts have a broad application prospect in the field of fuel cell catalytic materials. In this study, chloroplatinic acid, nickel nitrate hexahydrate and chloroauric acid were used as metal precursors to prepare Pt₃NiAu_x (x=0, 0.5, 1, 1.5, 2, 3) nano alloys by the sol-gel method, and their crystal structure, surface morphology and phase composition were analyzed. The results indicate that there are two main phases in Pt-Ni-Au alloy nanomaterials, namely (Au) and (Au, Pt, Ni). The addition of Au has a stabilizing effect on Pt-Ni nano particles, but it will also increase the size of nano particles. Therefore, it is necessary to prepare Pt-Ni-Au nanostructures with excellent performance by accurately controlling of Au doping amount.
