Kovalska E. Catalytic СVD-synthesis of carbon nanotubes, their modification and application

The thesis is devoted to establishment of regularities of catalytic synthesis of carbon nanotubes with usage of new three-component catalysts and to determination of influence of modifier's nature on physical and chemical properties of carbon nanotubes (CNTs) to obtain their stable dispersions in solutions and creation of catalytic system based on nanotubes. New oxide [Al, Fe/Ni, Mo]-containing catalysts for synthesis of CNTs from hydrocarbons were obtained by precipitation and aerosol method. CVD-synthesis of multi-walled CNTs (MWCNTs) and their conditioning and modification was made. Stable suspension based on MWCNTs was prepared with proportional allocation of deagglomerated particles of 150-400 nm. The methods and ways of regulation of hydrophobic and hydrophilic characteristics of CNTs were determined by oxidation and thermal treatment in an inert atmosphere. A catalytic "СехОу/MWCNT" system (with weight modifier 5.2%) effective in butanol-1 conversion was created. It was found that the alcohol transformation occurs by dehydrogenation.
