报道一种直接合成纳米碳管衍生材料的方法.利用纳米碳管的表面张力和毛细管作用,经过注入和选择冲洗法的两步法,制备填充铁、钴和镍的纳米碳管.通过选择合适的注入和洗脱溶液,金属粒子只会填充在纳米管内部.使用扫描电镜和扫描透射电镜研究证实金属粒子仅存在于纳米碳管内部.
A straightforward method is presented to produce catalyst particle-filled carbon nanotubes. Based on capilla￣rity and surface tension, a simple strategy was developed to selectively fill carbon nanotubes with Fe, Co, and Ni species using a two-step method consisting of impregnation and selective washing. By chosing the impregnation and washing solution properly, metal particles are produced exclusively inside the nanotubes. STEM and SEM investigations confirm the location of these metal particles is only inside the carbon nanotubes.
