Yield and Morphology of Longer Carbon Nanotubes Grown in the Presence of Sulphur

摘要

The growth of longer carbon nanotubes (CNT) is one of major challenges of CNT research. We recently reported the water vapor influence on the growth of longer CNT from ethylene-based feedstock [1]. It was shown that although water addition allows growth of centimeter-long aligned CNT, it is necessary to introduce extra growth activators, e.g. sulphur-containing compounds in order to enhance yield. It is known however that sulphur influence is controversial and requires additional research.
