Development of TiO2-Based Photocatalyst Supported on Ceramic Materials for Oxidation of Organic Pollutants in Liquid Phase

Water scarcity is one of the major concerns this century. The photocatalysis through TiO2 can be suitable for improving liquid wastewater treatment. However, used as a powder (nanoparticles), which drawback full-scale applications. To overcome this, in present work, was impregnated on ceramic material. Several parameters, such support cleanliness, load, suspension concentration, dispersion solvent, contact method, and drying temperature, were evaluated impregnation method. influence concentration suspensions tested from 1 to 10% w/w. results showed that preparation conditions impact yield. 10%TiO2/Leca most effective but had relevant loss by erosion. For 3.6%TiO2/Leca 5%TiO2/Leca, at concentrations 86.6 102.5 mg/L promoted 71 85% sulfamethoxazole removal 6 h under UVA radiation, respectively. Scanning electron microscopy (SEM) revealed adhesion onto surface material, thickness layer over attain 7.64 10.9 μm. work method Leca could obtaining cost-effective photocatalysts.
