This work examines the recent developments in non-traditional catalyst-assisted chemical vapour deposition of carbon nanotubes (CNTs) with a view to determining the essential role of the catalyst in nanotube growth. A brief overview of the techniques reliant on the structural reorganization of carbon to form CNTs is provided. Additionally, CNT synthesis methods based upon ceramic, noble metal, and semiconducting nanoparticle catalysts are presented. Experimental evidence is provided for CNT growth using noble metal and semiconducting nanoparticle catalysts. A model for CNT growth consistent with the experimental results is proposed, in which the structural reorganization of carbon to form CNTs is paramount.
本工作考察了近年来非传统催化剂辅助化学气相沉积碳纳米管（CNT）的最新发展，以期确定催化剂在纳米管生长中的重要作用。简要概述了依赖于碳的结构重排形成 CNT 的技术。此外，还介绍了基于陶瓷、贵金属和半导体纳米颗粒催化剂的 CNT 合成方法。提供了使用贵金属和半导体纳米颗粒催化剂生长 CNT 的实验证据。提出了一个与实验结果一致的 CNT 生长模型，其中碳的结构重排对于形成 CNT 至关重要。
