Photodegradation of organic pollutants RhB dye using UV simulated sunlight on ceria based TiO₂ nanomaterials for antibacterial applications.

ABSTRACT: To photo-catalytically degrade RhB dye using solar irradiation, CeO₂ doped TiO₂ nanocomposites were synthesized hydrothermally at 700 °C for 9 hrs. All emission spectra showed a prominent band centered at 442 nm that was attributed to oxygen related defects in the CeO₂-TiO₂ nanocrystals. Two sharp absorption bands at 1418 cm^-1 and 3323 cm^-1 were attributed to the deformation and stretching vibration, and bending vibration of the OH group of water physisorbed to TiO₂, respectively. The photocatalytic activities of Ce-TiO₂ nanocrystals were investigated through the degradation of RhB under UV and UV+ visible light over a period of 8 hrs. After 8 hrs, the most intense absorption peak at 579 nm disappeared
