摘要：

不引入其他还原剂，在多壁碳纳米管（MWCNTs）和铂镍前驱体存在的条件下，采用直接热解方法，在MWCNTs表面制备出Ni掺杂的铂基催化剂（Pt_xNi_y/MWCNTs）.通过XRD和EDX的测试证明了Pt-Ni纳米颗粒在MWCNTs表面的生成.TEM的照片表明样品颗粒的平均粒径在4～8nm.在碱性溶液中，利用CV方法测试了制备的Pt_xNi_y/MWCNTs催化剂对乙醇氧化的电催化行为.结果显示，Pt₁Ni₁/MWCNTs在所制备的催化剂中对乙醇的电化学氧化具有高的催化活性.

Abstract：

In the absence of other reducing agents, multi-walled carbon nanotubes(MWCNTs) supported Pt-Ni bimetallic catalysts were prepared for the first time by a facile method of pyrolysis.XRD and EDX analysis strongly demonstrated the formation of Pt-Ni nanoparticles on the surface of MWCNTs.TEM images revealed that the average particle sizes ranged from 4 to 8nm.The electrocatalytic activities of Pt_xNi_y/MWCNTs towards ethanol oxidation reaction(EOR) were investigated by CV, revealing that the catalyst of Pt₁Ni₁/MWCNTs has the best electrocalytic activity toward EOR among the as-prepared catalysts.
