摘要
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.
In this paper the MWCNTs were modified by poly (N-vinyl-2-pyrrolidone) (PVP) to support Pd nanoparticles, which were used as the catalysts for formic acid electrooxidation. And the performance of Pd/PVP- MWCNTs catalysts was studied by electrochemical measurements. The observations from Fourier transforms infra- red spectroscopy(FTIR) and transmission electron microscopy (TEM) illustrated that the Pd nanoparticles with a small size and narrow size distribution were highly dispersed on PVP-MWCNTs support. Therefore, the Pd/PVP- MWCNTs catalysts showed excellent ctalytic activity for formic acid electrooxidation.
