摘要: In this report, a low-cost and high performance PdSn@Pt/C catalyst with core–shell structure is prepared by two-stage route. X-ray diffraction (XRD) transmission electron microscopy (TEM) examinations show that the composite particles distribution quite homogeneous has surface area an average diameter of ca. 5.6 nm. The oxygen reduction reaction (ORR) activity was higher than commercial Pt/C catalyst. Catalytic studied cyclic voltammetry. High electrocatalytic activities could be attributed to synergistic effect between Pt PdSn.
