摘要

用氨基官能化碳纳米管(MWCNTs-NH2)包裹含羧基取代物的双核金属酞菁Fe2Pc2(CP)4,以通过简单的“原位”酰胺化反应增强对氧还原反应(ORR)的电催化活性。通过扫描电子显微镜(SEM)、X射线衍射、紫外-可见光谱(UV-Vis)、傅立叶变换红外光谱(FTIR)和X射线光电子能谱对Fe2Pc2(CP)4/MWCNTs-NH2复合材料的形态特征和化学环境进行了表征。采用循环伏安法和线性扫描伏安法对ORR的电催化活性进行了测试和分析。结果表明,Fe2Pc2(CP)4和MWCNTs-NH2之间的π–π相互作用显著提高了共轭结构中的π电子密度,并且可以更容易地还原氧。此外,对于Fe2Pc2(CP)4/MWCNTs-NH2催化剂,氧还原反应主要进行一步四电子过程。将M2Pc2Rn负载到功能化碳纳米管上后,其分散性和电催化性能得到了提高。

The enhanced activity of dinuclear metallophthalocyanines amino-functionalized carbon nanotube-based oxygen reduction reaction catalysts
Dinuclear metallophthalocyanines Fe2Pc2(CP)4 containing carboxyl substitutes were wrapped with amino-functionalized carbon nanotubes (MWCNTs-NH2) to enhance electrocatalytic activity for oxygen reduction reaction (ORR) using a facile “in situ” amidation reaction. The morphological characteristics and chemical environment of the Fe2Pc2(CP)4/MWCNTs-NH2 composites were characterized by scanning electron microscope (SEM), X-ray diffraction, Ultraviolet–visible (UV-Vis), Fourier Transform infrared (FTIR), and X-ray photoelectron spectroscopy. The electrocatalytic activity of ORR was tested and analyzed by cyclic voltammetry and linear sweep voltammetry. The results showed that the π–π interactions between the Fe2Pc2(CP)4 and MWCNTs-NH2 dramatically enhanced the π electron density in the conjugated structure, and oxygen could be reduced much more easily. Moreover, the oxygen reduction reactions mainly proceeded a one-step four electron process for Fe2Pc2(CP)4/MWCNTs-NH2 catalysts. The dispersion and electrocatalytic performance of M2Pc2Rn had be enhanced after being loaded on functionalized carbon nanotubes.
