Nd修饰的PtSn/C催化剂对乙醇的电催化氧化性能

Electroactivity of Nd Modified PtSn/C Catalyst for Ethanol Electrooxidation

利用浸渍还原法,以甲酸为还原剂制备了PtSnNd/C和PtSn/C纳米催化剂。XRD测量了催化剂的粒径和晶格参数,循环伏安法和计时电流法测试了催化剂对乙醇的催化氧化性能。结果表明,添加Nd可以明显提高PtSn/C催化剂对乙醇的电催化氧化活性,峰电流密度增大了86%。

The PtSnNd/C and PtSn/C nanoparticle catalysts were prepared by impregnation - reduction method using formic acid as a reductant. The particle size and lattice parameter of the catalysts were determined by XRD. Their catalytic activity for ethanol oxidation was evaluated by votammetry and chronoamperometry. It was found that the addition of Nd to PtSn/C significantly enhanced its catalytic activity for ethanol oxidation and the peak currem density on PtSnNd/C increased by 86% compared with PtSn/C.
