Preparation and Characterization of Coated ZnO Nanoparticles

Abstract:

SiO2 coated and SiO2/Al2O3 coated nano-ZnO were synthesized by chemical liquid deposition method. The surface properties and dispersion stability of the coated and uncoated ZnO nanoparticles were characterized. The results showed that a SiO2 or SiO2/Al2O3 amorphous layer was coated on the ZnO nanoparticles. The adsorbed hydroxyl content of ZnO was found to increase accompanied by the decrease of UV-shielding ability by surface modification; moreover, the isoelectric point of ZnO slurry was changed, and the stability of nano-ZnO in water was also improved effectively.
