摘 要：<正>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 condi- tions 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）,thermogravimetric analysis-differential scanning calorimeter（TGA-DSC）and vibrating sample magnetometer（VSM）.The results of magnetic measurements showed that the specific saturation magnetization（σ_s）and coercivity values（H_c）of nickel nanorods were 37.5 emu/g and 68.5 Oe,respectively.
