Abstract

A simple, time effective and cost effective, method was reported for synthesis of Nickel Oxide nanostructure. The NiO nanostructure was synthesized by gamma-irradiation method from NiSO4 precursor. The solution was irradiated by 60 Co gamma-ray source at the dose rate of 40 Gy/min for determined time. The synthesized powders are characterized by means of X-ray powder diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDX), Scanning electron microscopy (SEM), and Fourier transform infrared (FT-IR) spectroscopy. The XRD and FTIR results confirmed the formation of high pure phase of NiO nanostructure. Results of scanning electron microscope (SEM) images showed that product has flowe-like nanostructure morphology with average particle size of 60 nm. The mechanism of product formation through water Radiolysis was discussed. Three main stages can be considered for the radiolytic reactions of water in different time scales. (a) The physical stage (1 fs after the initial radiation interaction), (b) Physico-chemical stage (10 − 15 – 10 − 12 s), (c) The chemical stage (10 − 12 – 10 − 6 s).
