Composite TiO2-REOx Photocatalysts for Water Treatment
Original language description
In the present work, various methods were used for the fabrication of composite TiO2 films for photocatalytic removal of two model aqueous pollutants, dye Acid Orange 7 and the herbicide monuron. These composite films consisted of an underlying particulate TiO2 (TP) photocatalyst layer (prepared by drop-casting) and overlayer based on colloidal SiO2 and tetraethoxysilane as a film-forming substance, TiO2 particles and various rare earth oxides (REOx) – CeO2, Er2O3, Yb2O3 or La2O3. It was found that such an overlayer significantly improved the mechanical properties of the resulting coating. Furthermore, modification by composite overlayer containing REOx nanoparticles resulted in a significant increase of the rate of photocatalytic degradation of the herbicide monuron, as an example of a non-polar water pollutant.
