Abstract

A monodispersive core-shell structure of spherical mesoporous silica @nanocrystalline zirconia has been successfully synthesized by a special two step synthesis combined with a facile grafting method using plenty of surplus hydroxyls on the surface of mesoporous SiO₂. XRD, nitrogen adsorption analysis, TEM, FETEM, and UV-VIS are used for the structural characterization. This spherical composite has a very uniform particle size around 260 nm and a homogeneous single-particle shell of nanocrystalline zirconia of around 4 nm in thickness. UV-VIS spectrum of this composite presents a significant blue shift compared to the bulk crystalline zirconia.
