The review of the modern results in field of the preparation and computational simulation of the nanostructures based on the titanium carbide as a typical member of the broad family of d and f metal car- bides is presented. The possible routes of the synthesis of various Ti-C nanostructures: molecular clus- ters, nanocrystallites, nanospheres, nanowires, nanorods etc. are summarized; the morphology, atomic structure and the available physico-chemical properties are described. The theoretical models of the atomic structure and properties of the novel types of nanoforms for the system Ti-C (endo-, exo-titanofullerenes, "hybrid" Ti-C nanostructures based on the carbon nanotubes - so called nano-peapods, nano-cables) are presented. The possible applications of Ti-C nanomaterials - for hydro- gen storage, as the components of nanoceramics or as spintronic materials are discussed.
