Preparation and electrocatalytic performance of PtPb anode catalyst supported on carbon fiber

  • 摘要: 以静电纺丝技术与烧结工艺相结合的方式制备了碳纤维基PtPb纳米催化剂,并采用X射线衍射(XRD)、红外光谱(FT-IR)、扫描电镜(SEM)等分析测试手段对其进行了表征。结果表明,在预氧化温度为300 ℃、碳化温度为800 ℃的条件下,所制备的PtPb阳极纳米催化剂结晶程度好、比表面积大,粒径约为3.05 nm,催化活性颗粒均匀分散在多孔碳纤维骨架上。采用循环伏安法(CV)及交流阻抗(EIS)评价了该催化剂对乙醇氧化反应的电催化性能。结果表明,最大峰电流密度达到125 mA/cm2,电荷转移电阻相较于700 ℃下降了近60%。
