Abstract

Abstract:

The sol?gel method was used to modify the multi?walled carbon nanotubes, so that SnO₂ was combined with MWCNTs and doped with Cu ions. The samples M, M+Cu, M+Sn, and M+Sn+Cu were characterized by SEM, XRD, and FTIR. The surface microstructure was analyzed. The static adsorption method was used to measure the saturated adsorption capacity of different samples to VOCs. The VOCs gas volume concentration, temperature, and effects of metal doping were analyzed respectively. The results show that the saturation adsorption capacity of the four adsorbent samples is linearly related to the volume concentration and temperature of VOCs, and the larger the value of the two samples, the smaller the saturation adsorption capacity; at normal temperature (25 ℃) and normal pressure, MWCNTs adsorption capacity is almost 0, the saturation adsorption capacity of M+Cu is slightly smaller than M+Sn, and the adsorption capacity of M+Sn+Cu is about twice of M+Sn, up to 37.4 mg/g.

摘要：

采用溶胶?凝胶法对多壁碳纳米管进行改性，使SnO₂与MWCNTs复合并掺杂Cu离子。通过SEM、XRD、FTIR对样品M、M+Cu、M+Sn和M+Sn+Cu进行表征，分析其表面微观结构，用静态吸附法测量了不同样品对VOCs的饱和吸附量，并分别从VOCs质量浓度、温度影响等方面进行了分析。结果表明，4种吸附剂样品的饱和吸附量与VOCs质量浓度和温度呈线性相关，且二者数值越大，饱和吸附量越小；在常温（25 ℃）常压下，MWCNTs对VOCs气体的吸附量几乎为0，样品M+Cu的饱和吸附量略小于样品M+Sn，样品M+Sn+Cu的吸附效果最佳，约为M+Sn的2倍，可达37.4 mg/g。
