Generation of hydrophilic, bamboo-shaped multiwalled carbon nanotubes by solid-state pyrolysis and its electrochemical studies.

摘要: A simple, efficient, and novel method was developed for the direct preparation of hydrophilic, bamboo-shaped carbon nanotubes by pyrolysis ruthenium(III) acetylacetonate in a Swagelock cell is reported. The obtained product exhibits mostly bamboo-shaped, straight, periodic twisted, multiwalled possessing diameters 50−80 nm lengths around 10 μm. pyrolyzed characterized scanning electron microscopy (SEM), transmission (TEM), high resolution TEM (HRTEM), Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), micro-Raman, cyclic voltammetric techniques. HRTEM studies showed that walls consisted oblique grapheme planes with respect to tube axis. interlayer spacing between two graphitic layers found be 0.342 nm. XPS measurements have suggested as-prepared consist surface functional groups on nanotubes. electr...
