用聚乙烯吡咯烷酮(PVP)修饰的多壁碳纳米管(MWCNTs)作为Pd纳米粒子的载体,制得了Pd/PVP-MWCNTs催化剂,并研究了其对甲酸氧化的电催化性能.红外光谱仪(FTIR)和透射电镜(TEM)观测结果表明,Pd/PVP-MWCNTs催化剂中的Pd纳米粒子平均粒径小、分散性好.因此,Pd/PVP-MWCNTs催化剂对甲酸电氧化有很好的电催化性能.
The Pd / PVP-MWCNTs catalysts were prepared by using multi-walled carbon nanotubes (MWCNTs) modified with polyvinylpyrrolidone (PVP) as support for Pd nanoparticles. The electrocatalytic performance of Pd / PVP- The results showed that Pd / PVP-MWCNTs exhibited good electrocatalytic activity for formic acid electrooxidation because of their small average particle diameter and good dispersion.
