Synthesis and characterization of nanosized thin films of TiO2 and ZnO and photodecomposition of hazardous dye by thin films

Bharat N.Patil, V.S.Shrivastava

Fabrication of high quality ZnO and TiO2 thin films and analysis on its physical, chemical properties have application to remove dye from wastewater. In the present investigation highly textured semiconductor thin films were prepared by chemical bath deposition on glass substrate. The thin films were characterized byXRD, SEManalysis. The standard polycrystalline textured thin films contain nanograins were observed by XRD. SEM reveals the presence of adherent thin films. Photodecomposition of methylene blue from wastewater was possible by thin films.
