TITANIUM NANOCARBIDES: SYNTHESIS AND MODELING

The present state of research on the production and modeling of nanostructures based on titanium carbide – a typical representative of an extensive class of carbides of d- and f-metals – is reviewed. Methods for the synthesis of various Ti–C nanostructures (molecular clusters, nanocrystallites, nanospheres, nanofibers, nanowires) are examined, and their morphology, atomic structure, and known physicochemical characteristics are described. Theoretical models of the atomic structure and properties of new types of nanostructures in the titanium–carbon system (endo- and exohedral titanofullerenes, “hybrid” structures based on carbon nanotubes, the so-called peapods, nanocables, and a number of others) and the prospects for their application as components of nanoceramics, hydrogen accumulators, materials for spintronics, etc. are discussed.
