Synthesis of few-wall carbon nanotubes using methanol/ propanol mixture by chemical vapour deposition

摘要

Carbon nanotubes with few walls are highly appreciated for specific physiochemical properties and technological with huge applications. In this paper, we present an alternative process that can lead to lowering the manufacturing in time and cost. The process of synthesized were done by chemical vapor deposition with homemade portable tube furnace reactor. Methanol/ Propanol mixture is utilized as a source of carbon on silica surface caver with carbon black (CB) as support for growth CNTs at two temperature 450 and 750°C. The characterization of FWNTs was performed by X-Ray diffraction, Raman spectroscopy, transmission electron microscopy TEM, Brunauer, Emmett and Teller BET and Thermalanalysis TGA. The main interest of this study are to give the basis of an efficient simple synthesis process to produce CNTs of few walls for removing pollutant by adsorption. The method was succeeded to synthesize FWNT450 which more surface area and more active site than FWNT750 in adsorption properties.
