摘要/Abstract

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.

关键词: 聚乙烯吡咯烷酮, 多壁碳纳米管, Pd催化剂, 直接甲酸燃料电池

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

Key words: Poly(N-vinyl-2-pyrrolidone), multi wall carbon nanotubes, Pd catalyst, direct formic acid fuel cell
