摘要

We demonstrate structural transitions of carbon nanotubes using Raman spectroscopy under air, Ar, and mixed H-2 (10%)/Ar atmospheres. In the H-2 (10%)/Ar atmosphere, the G-mode peak shifted toward lower frequency with increasing temperature, which occurred to a far lesser extent in air and Ar atmospheres. This indicates that H-2 reacts more actively with surface carbon atoms in graphene layers than with others because of an etching effect. The temperature coefficients of the frequency changed from -0.014 to -0.018 with an increase in the carbon-carbon distance.
