Preparation and Characterization of PtSnFe/C Catalyst and Its Catalytic Activity for Ethanol Electrochemical Oxidation

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.
