, PP. 96-100
Keywords: 直接乙醇燃料电池（defc）,阳极催化剂,静电纺丝,乙醇电氧化
Abstract:
？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3.05nm，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125ma/cm2，电荷转移电阻相较于700℃下降了近60%。
