High Pressure Synthesis of Titanium Selenide (TiSe₂) Nanorods

High pressure (2 GPa) reaction method has been developed for synthesis of nanocrystalline titanium selenide (TiSe₂) rods in a short time (50 min). The obtained material was characterized by X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM). XRD data reveals that material possesses hexagonal structure with similar unit cell constants of bulk TiSe₂. Hexagonal rods like morphology with diameter of 30 nm and polycrystalline nature of the material was confirmed by HRSEM and HRTEM, respectively. We have demonstrated an ultra-fast fabrication technique of TiSe₂ nanorods which may also provide general approach for synthesis of other transition metal di-selenides.
