摘要：

Nickel oxide (NiO) nanostructures were synthesized by hydrothermal method using ethylene glycol and double distilled water as solvent in 3:2 volume ratio. The synthesized nanostructures were characterized by XRD, FESEM, EDX, FTIR, and UV-visible spectroscopy. XRD result shows that the synthesized nanostructures are polycrystalline in nature. FESEM images show the growth of NiO nanowires. The elemental compositions of the samples were analyzed by EDS. Fourier transform infrared (FTIR) spectroscopy confirms the existence of Ni-O bond in the sample. Optical band gap energy of about 3.71 eV was calculated from the UV-visible absorption measurement.
