A comprehensive review of FCCVD for carbon nanotubes growth

Abstract

Carbon nanotubes (CNTs) have emerged as a highly regarded material in this century, garnering significant attention across various fields. As the demand for high-quality CNTs synthesized at low cost and on a larger scale continues to grow, researchers face numerous challenges. Although the development of floating catalyst chemical vapor deposition (FCCVD) synthesis processes has enabled the continuous generation of CNTs, achieving low-cost, large-scale synthesis of high-quality CNTs remains a significant hurdle. Among the primary challenges are the optimization of synthesis equipment and the characterization of CNTs. This review begins by examining the advancements in FCCVD synthesis of CNTs and the underlying growth mechanisms. It then discusses the role of FCCVD in the carbon nanotube growth process, with a focus on its operational parameters. Then, based on the performance differences of carbon nanotubes, the applications of FCCVD-grown CNTs in different fields are introduced. Finally, this paper anticipates the prospects of synthesizing high-quality CNTs through FCCVD and offers reasonable suggestions for future research directions.
