Abstract
Multi walled carbon nanotubes (MWCNTs) were decorated by activated carbon nanoparticles of resorcinol-formaldehyde aerogels. Carbon nanospheres and MWCNTs were mixed by equal mass ratios for different durations. The products were characterized by Raman spectroscopy, thermal gravimetric analysis, nanoscanning electron microscopy, transmission electron microscopy and x-ray diffraction. The results indicated that a significant decoration with carbon nanoparticles occurred onto the MWCNTs.
Highlights
Carbon nanotubes (CNTs) drew a remarkable attention from their first discovery
It is noteworthy to declare that the Raman spectra can be utilized to estimate the degree of defects or disorders of Multi walled carbon nanotubes (MWCNTs) and resorcinol-formaldehyde activated carbon aerogel (RFA)-carbon nanoparticles (CNp)
The carbon-carbon decoration, MWCNTs with carbon nanoparticles, is a novel trend that can lead to expanding the potential applications of such nanomaterials
Summary
Carbon nanotubes (CNTs) drew a remarkable attention from their first discovery. This is attributed to their unique features, such as mechanical properties, electric properties, thermal stability, high chemical resistance and large surface areas[1]. The higher crystallinity in MWCNTs than RFA-CNp is due to the graphitic portion that results in the high order of MWCNTs’ structures. It is noteworthy to declare that the Raman spectra can be utilized to estimate the degree of defects or disorders of MWCNTs and RFA-CNp. The three fingerprint bands of pristine MWCNTs are the D-band at 1314 cm−1, G-band at 1576 cm−1 and G’-band at 2625 cm−1.
