Aligned multi-walled carbon nanotubes and nanofiber films were grown in quartz tube reactor by an injection chemical vapor deposition method. Various carbon materials were produced with different carrying gas in the same system. Scanning electron microscope images, transmission electron microscope images and Raman spectrum reveal that carbon nanofibers synthesized in inert gases have highly crystalline properties and iron particles were circled with nanofiber wall, and carbon nanotubes with hollow cavity were prepared in hydrogen gas. The distribution of diameters was controlled by changing the ratio of hydrogen to inert gases.

Key words: carbon nanotube, carbon nanofiber, injection CVD, carrying gas, morphology
