通过金属盐的热分解，在碳纳米管上生长了平均粒径分别为7 nm、8 nm、17 nm和8 nm的钯、铂、银和金纳米粒子。TEM观察表明，大部分合成的纳米颗粒粘附在碳纳米管的外表面。纳米颗粒的尺寸可以通过改变金属与碳的比例来调节。小的纳米粒子在电子束的强烈轰击下容易聚集。相比之下，使用相同的合成工艺在石墨或活性炭上几乎没有发现纳米颗粒。HRTEM和XRD研究表明，这些纳米粒子的结晶结构和晶格收缩。
By thermal decomposition of metal salts, palladium, platinum, silver and gold nanoparticles, with average size of 7 nm, 8 nm, 17 nm and 8 nm, respectively, were grown on carbon nanotubes. TEM observations showed that most of the nanoparticles synthesized stuck on the outer surface of the carbon nanotubes. The size of nanoparticles can be adjusted by changing the metal to carbon ratio. Small nanoparticles are prone to agglomerate under intense bombardment from the electron beam. By comparison, nanoparticles were scarcely found on graphite or active carbon using the same synthesis process. HRTEM and XRD investigations revealed the well-crystallized structure and a lattice contraction of these nanoparticles.
