NiO nanoparticles were synthesized by a two-step approach using a small amount of ionic liquid [Bmim][TfO] was found to be an effective stabilizing agent. The thermal, structural, morphological and magnetic characterization of the resulting samples were investigated by means of Thermogravimetry (TGA), X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Field emission scanning electron microscopy (FE-SEM), Transmission electron microscopy (TEM) and Vibrating sample magnetometer (VSM) analysis and the results indicate that the hexagonal β-Ni(OH)2 upon calcination at 400ºC to form cubic NiO nanoparticles and are superparamagnetic in nature. We believe that this method can be developed into a general way to synthesize other metal oxide nanoparticles on a large scale.
