Characterization of single-walled carbon nanotubes catalytically synthesized from alcohol
نویسندگان
چکیده
High purity single-walled carbon nanotubes (SWNTs) were synthesized from ethanol by catalytic CVD method. The yield of SWNTs was determined based on TGA complemented by Raman and TEM analyses. The effects of CVD reaction time and pre-reduction of catalytic metal on the yield and quality of synthesized SWNTs were investigated. The SWNT yield of more than 40% was achieved over the weight of zeolite support powder with Fe/Co catalyst, which corresponded to more than 800% yield over the weight of the catalytic metal, within the CVD reaction time of 120 min assuring as-grown high quality. 2003 Elsevier Science B.V.

متن کاملFluorescence spectroscopy of single-walled carbon nanotubes synthesized from alcohol
Abstract Near-infrared fluorescence measurements were performed on single-walled carbon nanotubes (SWNTs) catalytically synthesized from alcohol under various experimental conditions (alcohol catalytic CVD method, ACCVD). The chirality distribution was determined by measuring the fluorescence emitted from separated SWNTs as a function of excitation wavelength. Compared with HiPco SWNTs, chirali...

In this work the synthesis of polyaniline/chitosan/functionalized single- walled carbon nanotube nanocomposite is carried out. For this purpose single -walled carbon nanotubes were reacted with thionyl chloride to change the hydroxyl to acyl chloride groups for improving the react ability. In other step, aniline monomers and chitosan were polymerized in the presence of Iron (III) chloride to sy...
