摘要

The creation of nanoscale particles with well-defined structures has long been considered as a promising approach to generate materials with novel properties. Carbonaceous nano-particles (CNPs) with defined architectures, such as carbon nanotubes (CNTs), C_(60), carbon onions, carbon spheres, and carbon rods are particularly attractive owing to their unique electronic properties and many potential applications. At the same time, when these CNPs are regularly organized, additional functions appear. Such materials are believed to have hierarchic structures, in which the organization of the CNPs forms the first-order structure (FOS) and the configuration of the single CNP forms the second- or higher-order structure (SOS or HOS). Because both the FOS and HOS are responsible for the properties of the bulk material, simple methods to prepare multidimensional carbon materials with hierarchic structures are needed.
