Magnesium oxide nanoparticles were synthesized using Arabic gum as a biotemplate and
magnesium nitrate as the magnesium source by the sol-gel method. This method has many
advantages such as nontoxic, economic viability, ease to scale up, less time consuming and
environmental friendly approach for the synthesis of MgO nanoparticles without using any
organic chemicals. Nanoparticles were characterized by Fourier transform infrared (FT-IR)
spectroscopy, UV-visible spectroscopy and powder X-ray diffraction (XRD). The average
crystallite size of MgO nanoparticles was calculated using Scherrer formula and Williamson
Hall equation. The powder X-ray diffraction (XRD) analysis revealed the formation of cubic
phase MgO with average particle size of 14 (Scherrer formula) and 5.3 (Williamson Hall
equation) nm.
