Novel nanocomposite thin films for efficient degradation of Rhodamine B and Rhodamine 6G under visible light irradiation: Reaction Mechanism and Pathway studies

The present investigation aims to synthesize the novel nanocomposite thin film and utilize material remove emerging dyes efficiently (i.e., Rhodamine B (R-B) 6G (R-6G)), in an aqueous solution using LED visible light UV-A light. A facile synthetic route was adopted obtain TiO<sub>2</sub>-supported bentonite <i>in situ</i> decorated with Au nanoparticles (NPs) film. advanced analytical techniques characterizes materials. laboratory scale reactor utilized for efficient degradation of R-B R-6G catalysts. percentage removal 54.13% (visible light) 76.26% (UV-A R-6G, removed 60.37% 84.68% at initial pollutant concentration 0.5 mg/L pH 6.0 photocatalyst. parametric studies demonstrated insights mechanisms photocatalytic operations. significant mineralization these is achieved, repeated use operations indicated catalysts
