摘要
       The combination of one-dimensional and two-dimensional building blocks leads to the formation of hierarchical composites that can take full advantages of each kind of the materials, which is an effective way for the preparation of multi-functional materials with extraordinary properties. Among various building blocks, nanocarbons (e.g. carbon nanotubes and graphene) are one of the most powerful materials that have been widely used in human life. For instance, the theoretically proposed graphene/single-walled carbon nanotube (G/SWCNT) hybrids by placing SWCNTs vertically to graphene planes through covalent C-C bonding are expected to be with extraordinary physical property, intrinsic dispersion, and promising applications. However, the G/CNT hybrids that have been fabricated differs a lot with the proposed G/SWCNT hybrids because either the covalent C-C bonding is not well constructed or only multi-walled CNTs/carbon nanofibers are available in the hybrids. Herein, the catalytic nanofabrication of hierarchical sp2 nanocarbon materials is introduced. Their energy storage appplications for Li-ion batteries and Li-S batteries are also presented. Such novel hierarchical sp2 nanocarbon can not only be served as a prototype to shed a light on the chemical principle of G/CNT synthesis, but also serve as a platform for further applications in the area of heterogeneous catalysis, cell culture, drug delivery, electrochemical energy storage, and so on.
