摘要：

We report here the synthesis of nickel oxide (NiO) nanoparticles by microwave-assisted method, using a common precipitating agent followed by calcination at 400 degrees C. The effect of the microwave and pH on the crystallite size, morphology, structure, energy band gap and surface area of NiO have been investigated by means of powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), Fourier transform infrared spectroscopy (FTIR), ultraviolet visible spectroscopy (UV-vis) and BET surface area studies. It was observed that on increasing the volume of NaOH, the optical band gap energy (2.85-2.95 eV) and specific surface area (33.1-39.8 m(2)/g) increases, however the average particles size decreases (16.5-14 nm).
