The nano-NiO was prepared by hydrothermal synthesis method, using nickel sulfate hexahydrate as raw materials, urea as precipitant, and long chain alkyl ionic liquid 1-hexadecyl-3-methyl-midazolium chloride as surfactant, respectively. X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), and other analytical methods were used to characterize the particle size, the phase and microstructure, and morphology of the prepared samples. Thermal stability of the samples was studied by thermogravimetry (TG). The molecular structure of nickel oxide was analysed by making use of the Fourier transform infrared spectroscopy (FT-IR). The results show that all the precursors synthesized via hydrothermal synthesis method were converted into NiO after sintering, and the obtained nano-NiO particles have good dispersibility and regular morphology, simultaneously possessing uniform size, and high purity. The samples prepared are belong to cubic structures with an average particle size of about 5-20 nm.
