我们提出了统计和宏观分析来估计单壁纳米管（SWNT）水辅助生长（超生长）的催化剂活性并表征 SWNT 森林。催化剂活性估计为 84% (+/- 6%)，是有史以来报道的最高水平。人们发现 SWNT 森林是一种非常稀疏的物质，其中 SWNT 仅占总体积的 3.6%。这种结构稀疏性被认为在实现高效增长方面发挥着关键作用。
We propose a statistical and macroscopic analysis to estimate the catalyst activity of water-assisted growth (super-growth) of single-walled nanotubes (SWNT) and to characterize SWNT forests. The catalyst activity was estimated to be 84% (+/- 6%), the highest ever reported. The SWNT forest was found to be a very sparse material where SWNTs represent only 3.6% of the total volume. This structural sparseness is believed to play a critical role in achieving highly efficient growth.
