γ-ray Radiation Induced Synthesis and Characterization of α-Cobalt Hydroxide Nanoparticles

A novel synthetic route has been developed to prepare alpha-cobalt hydroxide with intercalated nitrate anions It was successfully synthesized by gamma-ray irradiation under simple conditions, I e, air atmosphere, without base Under gamma-ray irradiation, it leads to the formation of layered cobalt hydroxynitrate compounds which have small crystalline size and have the role of a generator of hydroxyl anion. Structural and morphological characterizations were performed by using power X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and high resolution transmission electron microscopy (HR-TEM) The component and thermal stability of the sample were respectively measured by Fourier transform infrared (FT-IR) spectroscopy, elemental analysis, and thermal analyses, including thermogravimetry (TG) and differential thermal analysis (DTA)
