A method to decorate single-walled and multiwalled carbon nanotubes (CNTs) with metal nanoparticles (NPs) based on the formation of a CNT polyelectrolyte is reported. Such a method does not rely on CNT surface functionalization or the use of surfactants. It has been tested for gold (Au) and palladium (Pd). The resulting hybrids present metal NPs highly dispersed along the tube walls and with small size dispersion. The average diameters of the Au and Pd NPs were approximately 5 and approximately 3 nm, respectively. This method paves the way for large-scale decoration of CNTs with metal NPs.
本文报道了一种基于形成 CNT 聚电解质来修饰单壁和多壁碳纳米管 (CNT) 的金属纳米粒子 (NP) 的方法。该方法不依赖于 CNT 表面功能化或使用表面活性剂。已经对金 (Au) 和钯 (Pd) 进行了测试。所得的混合物表现出金属 NPs 高度分散在管壁上且具有小的尺寸分散性。Au 和 Pd NPs 的平均直径分别约为 5nm 和 3nm。该方法为 CNT 大规模修饰金属 NPs 铺平了道路。
