Supported TiO2 Catalysts for Photocatalytic Degradation of Aqueous Rhoda mine 6G Organic Contaminants in Aqueous Samples: A Model for Removal

Sara Brown

For the oxidation of numerous organic contaminants, photocatalysis has emerged as a promising new method that is environmentally friendly..

The heterogeneous photocatalytic degradation of Rhodamin 6G was investigated utilising TiO2-derived catalysts, included in water as suspension as well as supported in raschig rings, as a model for the removal of complex organic pollutants from industrial water effluents. We investigated the photo-degradation mechanism under UV and visible light.

When a substance comes into contact with photons with a high enough energy level, free radical processes begin to operate, activating the chemical reaction known as photocatalysis.
