Simple and Economical Method for the Preparation of MgO Nanostructures with Suitable Surface Area

Abstract

A facile and simple method was proposed to control the size and shape of the MgO nano structures with high surface area in the presence of efficient and cheap templates like PEG 200, PEG 600, PEG 4000 and sorbitol at low temperature within a little time. Nano rods and Nanoparticles have been achieved by applying these templates and altering other growth parameters. The products were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Thermo Gravimetric Analysis (TGA). The surface area of the samples was characterized by BET method. The effect of the growth parameters such as template, pH, Mg2+/template, molar ratio and temperature on the growth and morphology of MgO nano structures have been investigated in details. By tuning these parameters MgO nano rods and nano particles can be formed.
