TL;DR: In this article, a floating catalyst chemical vapor deposition method was employed to effectively control nitrogen content within the carbon nanotubes and modulate their structure, showing that the inner structure of CNTs displayed a regular morphology transition from straight and smooth walls (0.% nitrogen) to cone-stacked shapes or bamboo-like structure (1.5%), then to corrugated structures (3.1% and above).
