Photocatalysis by Titania Nanocomposites: Synthesis and Characterization of Nano Titania and Its Magnetic Composites for Photocatalysis Abdelhady Bashir Kashyout

Photocatalysis plays an important role in dealing with today?s challenges demand for drinking water and waste water treatment technology. This work involves two directions to improve photocatalytic efficiency with economical benefits by different modification methods. One is the preparation of nanosphere and mesoporous titania nanoparticles. The other, a magnetic photocatalyst was prepared by coating of spinel cobalt ferrite as magnetic core with an insulating silica layer and photocatalytic properties of the outer titanium dioxide shell. Utilization of solar energy for the environmental cleanup becomes the future goal of the scientists. New visible light magnetic ? titania photocatalysts that contain a small band gap semiconductor coupling open up new possibilities for the development of solar-induced, separation and recyclability photocatalytic materials.
