| 英文摘要 | in this paper, a noble-metal-free electrocatalyst based on carbon-supported zirconium oxynitride (zroxny/c) was prepared by ammonolysis of carbon-supported zirconia (zro2/c) at 950 degrees c and investigated as cathode electrocatalyst towards oxygen reduction reaction (orr) in pemfcs. the electrocatalyst was characterized by x-ray diffraction (xrd) and transmission electron microscopy (tem) techniques. the catalytic activity of the catalyst towards orr was investigated by using the rotating disk electrode (rde) technique in an o-2-saturated 0.5 m h2so4 solution. the zroxny/c electrocatalyst presented attractive catalytic activity for orr. the onset potential of zroxny/c electrocatalyst for oxygen reduction was 0.7 v versus rhe and the four-electron pathway for the orr was achieved on the surface of zroxny/c electrocatalyst. the zroxny/c electrocatalyst showed a comparatively good cell performance to orr in pemfcs, especially when operated at a comparatively high temperature.
