摘要/Abstract

摘要： 使用高分辨透射电镜和比表面孔径分析仪，采用Boehm’s滴定法和N₂吸附法，对不同条件酸处理得到的官能团化的碳纳米管进行了系统表征。研究发现碳纳米管是以管间堆积孔为特征孔的大中孔材料，酸化处理增加了管间堆积孔的孔容和比表面积，但对微孔和开口管腔孔有堵塞效应，该效应随着官能团的增加而明显。同时考察了总酸量对比表面积的影响，发现当总酸量在1 mmol·g^-1附近时比表面积较高。

关键词: 碳纳米管, 官能团, 孔结构, 比表面积, 化学滴定

Abstract: The functional carbon nanotubes(CNTs) under different acid treatment conditions are systematically characterized with Boehm’s titration method and the N₂ adsorption method using high-resolution transmission electron microscopy and specific surface area and pore size analyzer. The results show that the functionalized CNTs and pristine CNTs are characterized with aggressive meso-and large pores. Acid treatment increases the pore volume and specific surface area of these pores. The created functional groups jam the micropores and opened inner hollow pores. Such effect becomes drastically with the increasing of the amount of functional groups. The effects of total acid amount on specific surface area were also investigated and the optimal value is about 1 mmol·g^-1.

Key words: carbon nanotubes, functional group, pore structure distribution, specific surface area, chemical titration
