Abstract
In this study, sol–gel technique has been used to prepare nanoparticle Mg doped ZnO with 2 wt. % at low pH without using any capping or surfactant agent. The Mg-ZnO nanostructure, surface area and porosity, surface morphology and element analysis was analyzed by X-Ray Diffraction (XRD), Fourier Transforms Infra-Red (FTIR), N2 Physisorption and Field Emission Scanning Electron Microscopy with energy dispersive X-ray spectroscopy (FESEM-EDX). The characterizations confirmed that the surfactant is not necessary for sol-gel synthesis technique, whereby highly crystalline material with smaller crystallite size (30nm) and high surface area (21.7) was obtained. Besides, the synthesis approach is useful for accurately immobilized the required amount of Mg as doping element on ZnO material with the accuracy up to 99.5% confirmed through EDX analysis.

Materials in nanoscale in size will typically having higher surface area compared to their bulk counterpart of similar mass
ZnO and Mg-ZnO materials were prepared by using zinc acetate dehydrate Zn(CH3COO)2∙2H2O (99.5%), Magnesium (II) nitrate hexahydrate Mg(NO3)2∙6H2O (99.5%) and oxalic acid C2H2O4∙2H2O (99.5%) from (R&M chemicals), ethanol (99.99% ) from (Fisher chemical) and acetone CH3OCH3 (99.5%) from (Friendemann Schmidt chemical)
Summary
The important properties of nanostructured materials have started motivation among scientists to explore the possibilities of using them in various technological applications. The electronic and optical properties of nanostructured materials have been of interest because of their potential applications in the fabrication of microelectronic and optoelectronic devices [1,2,3]. Materials in nanoscale in size will typically having higher surface area compared to their bulk counterpart of similar mass. One benefit of greater surface area can dramatically improve the reactivity of surface dependent chemical processes especially in catalysis application. The physico-chemicals characteristics of nanoscale materials are size dependent and this offers the possibility for researchers either in academic or industry to fine-tune a material property of interest to suite their niche application[4]
