NOVELTY - Producing anorganic nanofibers and/or nanofibrous structures (410) comprising titanium nitride (TiN) involves dissolving polymer matrix (4) containing titanium alkoxide in solvent system on basis of alcohol containing chelating agent, poly(vinylpyrrolidone) and addition of concentrated hydrochloric acid through electrostatic spinning produced organic/anorganic nanofibers (41) arranged in nanofibrous structures subjected to calcination in air atmosphere at 350-800 degrees C and titanium dioxide (TiO2) nanofiber arranged in nanofibrous structure are annealed in stream of ammonia at 400-900 degrees C.    USE - For production of anorganic nanofibers and/or nanofibrous structures used in solar cells and electrodes for electrochemical cells (claimed) for conversion and storage of energy; used as support structure for catalysts.    ADVANTAGE - The method provides anorganic nanofibers and/or nanofibrous structures comprising titanium nitride (TiN) in pure state without residual titanium dioxide. Electrical conductivity and high specific surface enables a perfect distribution of electrons, which enables application at production of more efficient electrodes. TiN nanofibers improve mechanical properties of composite materials and products made of them, and simultaneously improves their anticorrosion properties. Inertness, high specific surface and accessibility of this surface enable usage of nanofibrous structure of TiN as a support structure for catalysts. The anorganic nanofibrous structure has high sintering ability. The ability can be e.g. used after grinding the fibers into individual particles and their further application for production of compact parts. At increasing the temperature above the temperature for preparation of nanofibers, the TiN nanocrystals are easy to sinter into greater aggregates and enable creation of dense and strong formations. The anorganic nanofibrous structure is a part of a composite (preferably bullet-proof material). The composite is material having a high wear resistance. It creates supporting structure with high accessible specific surface for catalysis.
