摘要: Abstract In this paper, carbon nanotubes synthesized by floating catalyst method were purified liquid-phase oxidation and treated hydrogen plasma with different time. The morphology microstructure of characterized transmission electron microscope (TEM), high-resolution (HRTEM), selected area diffraction (SAED) Raman spectroscope. results showed that bamboo-like structure changed solid helical the treatment for 5 h 10 h, intensity D peak in spectrum was larger larger. UV–vis absorption indicated redshifted, stronger narrower than untreated nanotubes. However, effect on FT-IR slight. probably made have important applications optical material controllable wavelength.
