Hydrothermal synthesis and characterization of NiS nanocrystals

Guoyan Li

Abstract

Nanocrystalline NiS was synthesized in a convenient hydrothermal way at relatively low temperature,using NiCl_(2)·6H_(2)O,Na_(2)S_(2)O_(3) or S=C(NH_(2))_(2) as reactant.Several techniques including XRD and TEM were used to characterize the products.The results showed that the prepared product was proved to be hexagonal NiS with morphology of irregular nanoparticles and that if using different sulphur sources and surfactant PVP,the morphologies of the NiS can be controlled.
