Preparation and Characterization of Coated ZnO Nanoparticles

摘要：

　　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.
