【Abstract】 The effects of impregnation and reduction conditions on the particle size of Pt and structure of Pt/C catalyst were investigated by TEM, XRD and rotating thin-layer electrode techniques. The results showed that reductants affected the particle size and crystal face of platinum in the catalyst and Pt/C catalyst prepared from BP-2000 and by using HCHO as reductant showed a good electrocatalytic activity.更多还原
