The aim is to create composites based on ceramic and carbon nanomaterials, which have improved functional properties. Operators have accumulated extensive experience in the synthesis of various carbon nanostructures and show that they can be used for sorbents of hydrogen fuel cell electrocatalysts and modifying additives in composite materials. There is experience for nanopowder production of metals and metal oxides, and a metal-carbon, carbon-polymer, carbon-ceramic and carbon-carbon composites. This experience and analysis of scientific and technical literature shows that functional properties of these composites is strongly dependent on the structure and method of obtaining a carbon material. Yes, as a catalyst carrier rather use coaxial conical carbon nanofibers and composite sorbents for hydrogen - plane-parallel nanofibers, as hardening additives to polymers - coaxial cylindrical carbon nanotubes. Even small additions (1-2% wt.) carbon nanotubes or nanofibers considerably increase the strength characteristics of composite materials, and improve electrical and thermal conductivity. It is well known that carbon nanostructures synthesis catalysts in most are metals of iron group (Fe, Co, Ni). After the nanostructures' synthesis the catalyst, whose content is 30 wt. %, eluted by boiling in acids. One of the objectives of this project is to develop catalysts based on hydrocarbons. Thus obtained nanostructured product will not require harmful chemicals and energy intensive stage of processing (cleaning).
