Structural, morphological and optical properties of MgO nanoparticles for antibacterial applications

Abstract Magnesium oxide (MgO) nanoparticles have been synthesized by wet chemical reaction method. The structural, optical and morphologies of MgO nanoparticles have been characterized by X-ray diffraction (XRD), UV–vis Spectrophotometry, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The synthesized nanoparticles were well-dispersed spherical nanoparticles with the average size of 16 nm. The SEM and TEM reveal the formation of almost spherical shaped MgO nanoparticles. XRD shows the face cubic centred structure of the MgO nanoparticles. The observed antibacterial properties, suggest the possible utilization of prepared nanoparticles in water purification.
