During the work, composites based on ceramic and carbon nanomaterials with improved functional properties were created, and as shown, the carbon nanostructures can be used to fabricate the sorbents of hydrogen, fuel-cell electrocatalysts, and modifiers in composite materials. Nanopowders of metals and metal oxides are obtained, and the carbon–ceramic composites are fabricated. As shown, the functional properties of such composites are strongly dependent on both the structure and the method of obtaining carbon material. As carriers of catalyst, the coaxial-conical carbon nanofibers are served, and for composite sorbents of hydrogen, plane-parallel nanofibers are used; as hardening additives to polymers, coaxial-cylindrical carbon nanotubes are applicable. As shown, even small additions (1–2 wt.%) of carbon nanotubes or nanofibers significantly improve both electrical conduction and thermal conduction.
