Formation of axial aligned polydisperse nanocarbon structures under gas-pyrolytic deposition from cyclohexane with ferrocene
Vertically aligned arrays of multiwall carbon nanotubes have been deposited on a single crystal silicon substrate by CVD method from cyclohexane with ferrocene as a catalyst. As a result of synthesis the axial polydisperse carbon microstructures combined from vertically aligned carbon nanotubes were produced. The structures investigations were carried out with the use of SEM Tescan Lyra3 FEG, Ntergra Spectra NT-MDT probe microscope, and Raman scattering method. The possibilities of puriication of synthesized carbon structures from amorphous carbon by oxidation with atomic oxygen and ozone have been studied with the purpose of signiicantly increasing their speciic surface area. Methods for the use of synthesized polydisperse structures as carriers of catalysts, solid electrolytes, carriers of chemical sensors, and also in absorption techniques for storing gases and liquids are proposed.
