Abstract
Abstract This investigation aims to study the characterization of MgO nanoparticles prepared using two different routes via microwave method and sol-gel route. The characteristics of the fabricated of MgO nanoparticles were examined by FESEM, XRD, FTIR and BET. The results of XRD for microwave method and sol-gel route revealed peaks indicating the uniform crystalline. The images of FESEM of MgO nanoparticles by microwave method evinced an irregular shape, but the MgO nanoparticles synthesized by sol-gel route were found crystallites, nano spherical shape. The results of this work manifested that the MgO nanoparticles prepared via sol-gel route had smaller grain size as (≈ 50 nm) compared to the microwave method (≈ 72 nm). The specific surface area of the MgO nanoparticles using sol-gel route was more than with microwave route. FTIR examination reveals that the presence of Mg-O in the sample.
