摘要：

Non-Pt electrocatalysts, Pd3Fe1/C, were doped with inorganic nonmetallic element phosphorus through electroless plating technique, and their electrocatalytic performance was studied. Electroless plating is an effective way to obtain P-doped Pd3Fe1/C with small particle size and high dispersion. The introduction of the P element leads to the decreased Pd-Fe particle size of the catalysts and an increased electrocatalytic activity for oxygen reduction. Moreover, the P dopant can improve the stability of Pd3Fe1/C to some extent. In the case of Fe/P molar ratio = 1/10, the Pd3Fe1P10/C catalyst exhibits the best performance.
