Multi-walled carbon nanotubes (MWCNTs) were directly fluorinated at different conditions. Fluorinated MWCNTs were impregnated with Co(NO3)2ㆍ6H2O solution. The changes of chemical and physical properties were investigated using BET surface area analysis, transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). A direct fluorination of MWCNTs has been carried out to obtain a series of fluorinated multi-walled carbon nanotubes. The strong fluorination on the MWCNTs leads breaking the bond of carbon-carbon, which makes carbon-flourine bonding. The fluorinated MWCNTs shows the new textural and cobalt dispersion properties. |
