Abstract

Carbon nanofibers CNFs were synthesized through nickel ion Ni

impregnation of powdered activated carbon PAC. Chemical Vapor Deposition CVD using acetylene gas, in the presence of hydrogen gas, was employed for the synthesis process. Various percentages 1, 3, 5, and 7wt. % of Ni

catalysts were used in the impregnation of Ni

into PAC. Field Emission Scanning Electron Microscope FESEM, Fourier Transform Infrared FTIR Spectroscopy, Energy Dispersive X-Ray Analyzer EDX, Transmission Electron Microscopy TEM, Thermal Gravimetric Analysis TGA, zeta potential, and Brunauer, Emmett, and Teller BET were utilized for the characterization of the novel composite, which possessed micro and nanodimensions. FESEM and TEM images revealed that the carbonaceous structure of the nanomaterials was fibrous instead of tubular with average width varying from 100 to 200 nanometers. The PAC surface area increased from 101m

-g to 837m

-g after the growth of CNF. TGA combustion temperature range was within 400C and 570C, while the average zeta potential of the nanocomposite materials was 24.9mV, indicating its moderate dispersive nature in water.
