报告摘要：

The accelerating energy consumption in modern society stimulates the rapid development of alternative energy technology to utilize energy resources in more efficient, clean and renewable manner. It has become extremely important to develop new energy conversion and storage systems. The performance of these devices intimately relies on the structure and properties of the component materials. Carbon nanomaterials, such as one-dimensional (1D) carbon nanotubes and two-dimensional (2D) graphene, have attracted great interest in recent years because of their unique structures, superior electrical and mechanical properties. However, these 1D and 2D nanomaterials exhibit extremely poor out-of-plane transport properties due to the weak van der Waals interaction in the transverse direction. Recent theoretical and experimental studies have indicated certain three-dimensional (3D) architectures could possess desirable out-of-plane properties while maintaining in-plane properties, which shows great potential applications in energy related applications.

 We have designed a series of novel three-dimensional carbon nanomaterials made of carbon nanotubes or graphene for energy conversion and storage, such as B, N doped graphene foams (Figure 1a) and nitrogen doped graphene foams (Figure 1a). Recnetly, we have developed a strategy of creating 3D graphene-CNT hollow fibers (Figure 1c) with radially aligned carbon nanotubes (RACNTs) seamlessly sheathed by a cylindrical graphene layer through a one-step chemical vapor deposition using an anodized aluminum wire template. These 3D carbon nanomaterials have been used for energy conversion and storage with high performance.
