摘　　要：Powders of hexagonal-structured single-crystalline nickel sulfide nanorods have been synthesized in cetyltrimethy ammonium bromide （CTAB）/water/hexane/n-pentanol quaternary microemulsion under hydrothermal conditions by using the reaction of carbamide and carbon disulfide as a sulfide source. Single-crystalline nickel nanorods have been synthesized via thermal decomposition by using single-crystalline nickel sulfide nanorods as precursor. The influence of different reaction parameters on the morphology of the products has been investigated. The structure, morphology and magnetic properties of the products were characterized by X-ray diffraction （XRD）, transmission electron microscope （TEM）, calorimeter （TGA-DSC） and vibrating sample magnetometer showed that the specific saturation magnetization （σs） and 37.5 emu/g and 68.50e, respectively. thermogravimetric analysis-differential scanning （VSM）. The results of coercivity values （Hc） magnetic measurements of nickel nanorods werePowders of hexagonal-structured single-crystalline nickel sulfide nanorods have been synthesized in cetyltrimethy ammonium bromide （CTAB）/water/hexane/n-pentanol quaternary microemulsion under hydrothermal conditions by using the reaction of carbamide and carbon disulfide as a sulfide source.
