This project aims at the development of the methods to tailor the photocatalytic activity of ZnO nanoparticles. Methods to both enhance and reduce the photocatalytic activity for specific applications will be investigated, and the physical and chemical mechanism of photocatalysis-control will be studied. The method developed will be applied for a commercial scale production of ZnO nanoparticles. The effects of (a) impurity doping inside of the particles, (b) particle coating, (c) size and morphologies of the particles, and (d) ion-adsorption of the particle surface, to the photocatalytic activity of ZnO nanoparticles will be investigated. The methods developed will be applied for a commercial scale production of ZnO nanoparticles by ANT.
