Abstract
Abstract Vertically aligned carbon nanotube (VACNT) materials is a promising candidate in different fields. The intrinsic performance of VACNTs, such as a large specific surface area, high conductivity, and especially its vertical conductive channel, stands out the VACNT-based device from conventional carbon material-based devices in the energy, environmental sustainability, and so on. In this review, a comprehensive and in-depth summary on the synthesis method and fundamental mechanisms, and design strategies for the novel VACNT materials, is presented. In addition, an overview of the latest development in high-efficiency utilization of VACNT materials in representative fields, including energy storage and conversion, catalysis, terahertz spectroscopy, biology and biomedicine, and environmental sustainability, is given. Finally, the challenges and promising perspectives of VACNT materials in future development are outlined.

Summary
Carbon nanotubes (CNTs) can be viewed as tubular structures made of curled graphene sheets. In. In this review, we focus on the recent progress on the VACNTs and their composites. The synthesis methods and mechanism were discussed and highlighted. Since the structure and morphology of the VACNTs play a critical role in its application in different fields, an important part of this review will focus on their synthesis mechanism. We discuss the applications of VACNTs for energy storage and conversion, THz, and environmental sustainability. Differing from the application of VACNTs in a single field, this review summarizes the applications and roles of VACNTs in various fields, giving the reader a new understanding of VACNTs. the main challenges, promising directions and potential application of VACNT are proposed to motivate next-generation VACNT-based novel device
