Abstract

Solvent mixed spray pyrolysis technique has attracted a global interest in the synthesis of nanomaterials since reactions can be run in liquid state without further heating. Magnesium oxide (MgO) is a category of the practical semiconductor metal oxides, which is extensively used as catalyst and optical material. In the present study, MgO nanoparticles were successfully synthesized using a solvent mixed spray pyrolysis. The X-ray diffraction pattern confirmed the formation of MgO phase with an excellent crystalline structure. Debye-Scherrer equation is used for the determination of particle size, which was found to be 9.2 nm. Tunneling electron microscope analysis indicated that the as-synthesized particles are nanoparticles with an average particle size of 9 nm. Meanwhile, the ultraviolet-visible spectroscopy of the resulting product was evaluated to study its optical property via measurement of the band gap energy value.

Assynthesized MgO nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and ultraviolet-visible (UV-VIS) spectroscopy

Summary

Introduction

Synthesis of metal oxide nanoparticles has attracted considerable attention [1, 2]. Abundant techniques have been developed to prepare nanoparticles of MgO. This nanoparticle has attracted much attention due to its wide band gap [3]. Lange and Obendorf studied the effect of plasma etching on destructive adsorption properties of polypropylene fibres containing magnesium oxide nanoparticles [5]. Jin and He demonstrated antibacterial activities of MgO nanoparticles against food borne pathogens [6]. Solvent mixed spray pyrolysis method was undertaken to prepare MgO nanoparticles. To the best of our knowledge, no report is present in the literature of material science on optical study of MgO nanoparticles synthesized by solvent mixed spray pyrolysis method. Assynthesized MgO nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and ultraviolet-visible (UV-VIS) spectroscopy
