| 摘 要： | 通过溶胶凝胶方法制备SiO2修饰的碳纳米管（SiO2-CNTs）为载体材料,利用微波辅助加热化学还原方法制备Pt/SiO2-CNTs电催化剂。然后分别利用扫描电子显微镜和能量散射谱仪对Pt/SiO2-CNTs电催化剂的表面形貌和元素组成进行了表征。在酸性介质中,采用循环伏安法研究了Pt/SiO2-C电催化剂对乙醇氧化的电催化活性。与商用催化剂PtRu/C电催化剂相比,在相同催化剂载量和实验条件下,Pt/SiO2-CNTs电催化剂具有更好的催化活性和抗CO中毒能力。

| Abstract: | The SiO2 modified carbon nanotubes were prepared through sol-gel method and used as catalyst support.The Pt/SiO2-CNTs were synthesized by microwave-assisted chemical reduction method.The micrograph and the elemental composition of Pt/SiO2-CNTs nanoparticles were characterized by scanning electron microscopy and energy dispersive X-ray spectroscopy,respectively.The electrocatalytic properties of Pt/SiO2-CNTs electrocatalyst for ethanol oxidation were investigated by cyclic voltammetry in acidic solution.Under the same catalyst loading mass and experimental conditions,the Pt/SiO2-C electrocatalyst shows higher catalytic activities than PtRu/C catalyst.It also possesses good anti-poisoning ability. |
