Structural properties and bonding characteristic of magnesium (Mg) doped zinc oxide (ZnO)

Abstract

Abstract Structural properties and bonding characteristics of Mg doped ZnO by co- precipitation methods were characterized by using X-ray Diffraction (XRD) and Fourier Transforms Infrared (FTIR) spectroscopy. The analysis of FTIR showed peaks at 466.77 cm −1 and 451.31 cm −1 which correspond to the stretching of the oxygen bond in the ZnO structure and leads to defect formation by the oxygen atom detachment. This defect occupied by the Mg atom and proved by the widening of peak oxygen. The data XRD showed increasing the average size of ZnO crystal from 27.74 nm to 38.17 nm with the addition of 10% wt of Mg. These phenomena indicated agglomeration of the partial displacement of O 2- by Mg 2+ in the MgZnO structure. This study showed simple methods to combine with Mg atom and ZnO to produce potential materials for catalytic applications.
