In this study, we demonstrated a novel method to grow carbon nanotubes (CNTs) by chloride-mediated chemical vapor deposition with hydride vapor-phase nucleated catalyst (HVPN). In the HVPN method, FeCl2 as a catalyst precursor was produced by an in situ chemical reaction between Fe powder and HCl gas. After the synthesis of FeCl2, CNTs were grown by supplying acetylene. We studied growth conditions for the catalyst formation process in HVPN method. High-quality CNT forests were grown by optimizing the FeCl2 synthesis conditions. This study has established the HVPN method as a novel, highly controllable way to grow CNT forests.

使用气相催化剂输送的碳纳米管生长新方法

在这项研究中，我们展示了一种通过氯化物介导的化学气相沉积和氢化物气相成核催化剂 (HVPN) 来生长碳纳米管 (CNT) 的新方法。在 HVPN 方法中，FeCl2作为催化剂前体，通过 Fe 粉末和 HCl 气体之间的原位化学反应产生。FeCl合成后2，通过提供乙炔生长碳纳米管。我们研究了 HVPN 方法中催化剂形成过程的生长条件。通过优化 FeCl 生长高质量的 CNT 森林2合成条件。本研究将 HVPN 方法确立为一种新颖、高度可控的 CNT 森林生长方式。
