摘要:

 以静电纺丝技术制备的石墨烯改性碳纤维为载体,将Pt–Sn纳米催化剂原位负载在碳纤维上。利用X射线衍射、透射电子显微镜表征催化剂的微观结构,利用循环伏安、计时电流和交流阻抗等分析催化剂的电催化活性,研究了石墨烯含量对燃料电池碳纤维基阳极催化活性的影响。结果表明:当石墨烯质量分数为3%时,催化剂表现出最佳的催化活性,循环伏安测试的峰电流密度达到119 mA/cm2。

 

 High–dispersed and well–distributed Pt–Sn catalyst supported on graphene–modified carbon fiber was prepared by an electrospinning method for direct ethanol fuel cell. The phase composition and microstructure of the catalyst were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The electrocatalytic activity was determined by cyclic voltammetry, chronoamperometry and alternating current impedance to investigate the effect of graphene content on the catalytic activity of anode catalyst. The results show that the catalyst supported on carbon fiber loaded with 3% (in mass fraction) graphene obtains an optimum electrocatalytic activity with a current density of 119 mA/cm2.
