中文摘要: 采用改进的浸渍还原法在低温下制备了Pd2Ni3/C纳米催化剂.TEM图像显示，催化剂的粒径较小，且均匀分散在碳载体表面；XRD图谱可以看出，Pd（111）衍射峰由于Ni的掺杂效应发生宽化，说明采用这种方法合成的Pd-Ni/C催化剂粒径较小；电化学测试表明，Pd2Ni3/C具有较高的甲酸电催化活性和稳定性.
Abstract:Carbon supported well-dispersed Pd-Ni composite nanocatalysts are synthesized by an improved impregnation reducation method in ice water bath environment.TEM images show that Pd-Ni nanoparticles are uniformly dispersion on carbon black.XRD analysis is conducted to broaden in Pd(111) diffraction peak for Pd2Ni3/C, demonstrating that Pd2Ni3 possesses smaller particle size due to Ni doping effect.Electrochemical measurement shows that Pd2Ni3/C has higher catalytic activity and stability towards HCOOH electrooxidation compared to Pd/C.
