Abstract

SiO(2) supported cobalt (Co) catalyst could be partially reduced and anchored by unreduced Co ions during a carbon monoxide (CO) chemical vapor deposition (CVD) process. This resulted in the formation of sub-nanometre metallic Co clusters catalyzing the growth of single-walled carbon nanotubes (SWNTs) with a narrow diameter distribution.

摘要

SiO(2) 负载的钴 (Co) 催化剂在一氧化碳 (CO) 化学气相沉积 (CVD) 过程中可能会被部分还原并被未还原的 Co 离子锚定。这导致形成亚纳米级金属 Co 簇，催化单壁碳纳米管 (SWNTs) 的生长，具有较窄的直径分布。
