Manufacture of Magnesium Oxide Nanoparticles Coated with Silica Shells

Abstract

MgO@SiO₂ core–shell nanoparticles were manufactured, and a synthetic protocol was developed to prepare MgO nanoparticles where the SiO₂ shell thickness was less than 10 nm. The influence of synthesis parameters on the formation of MgO@SiO₂ nanoparticles was studied. The fact of a SiO₂ shell being formed on the MgO surface was established and the sizes of the thus-prepared MgO@SiO₂ nanoparticles were determined by TEM and Fourier-transform IR spectroscopy.
