摘 要：
本文采用乙二醇还原法(EG法)制备出了PtSnFe/C三元催化剂,利用X射线衍射(XRD)、循环伏安扫描(CV)和电化学线性扫描(LSV)等手段对催化剂的结构和性能进行了表征,并计算了其电化学活性表面积(EC-SA)。实验结果表明:Fe的加入导致三元催化剂粒子的平均粒径变小;相对于Pt/C、PtSn/C和PtFe/C催化剂,PtSnFe/C催化剂具有较高的乙醇电化学氧化反应催化活性。

摘 要：
In this article,trinary PtSnFe/C catalyst was prepared by an ethylene glycol method(EG method),X-ray diffraction(XRD),cyclic voltammetry(CV),linear sweep voltammetry(LSV) measurements were carried out to characterized the structure and properties of the catalyst,and the electrochemical activity surface area(ECSA) was calculated.The experimental results show that the addition of Fe reduces metal catalyst particle size;comparing with the Pt/C,PtSn/C and PtFe/C catalysts,PtSnFe/C catalyst has higher ECSA and better catalytic activity for ethanol oxidation reaction.
