- Abstract
Hierarchical nanostructureds of β-NiS were successfully prepared by hydrothermal treatment of Ni(NO3)2.6H2O and thioglycolic acid (TGA) at 180°C. The as prepared β-NiS hierarchical nanostructureds were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible (UV-vis) absorption spectroscopy, photoluminescence (PL) spectroscopy and Fourier transform infrared (FT-IR) spectra. The hierarchical nanostructureds, with an average diameter of ∼600 nm, were composed of short nanorods with a diameter of ∼30 nm and a length of about 150 nm. On the basis of the experimental results and corresponding literatures, a possible growth mechanism of the NiS hierarchical nanocrystals is discussed. The obtained products have relatively high surface area, which favors the application in catalysis.
