Preparation and Characterization of Supported Molybdenum Doped TiO2 on α-Al2O3 Ceramic Substrate for the Photocatalytic Degradation of Ibuprofen (IBU) under UV Irradiation

TiO2-based photocatalyst materials have been widely studied for the abatement of contaminants emerging concerns (CECs) in water sources. In this study, 1.5 wt% Mo-doped HRTiO2 was obtained by sonochemical method. The material analyzed and characterized thermal, structural/textural, morphological, optical properties using TGA-DSC, XRD, TEM, FTIR, XPS, SEM-EDS, BET (N2 adsorption-desorption measurement BJH application method), UV-Vis/DRS measurement. By dip-coating technique, ~5 mg Mo/HRTiO2 as an active topcoat deposited on ceramic. suspension activity performance evaluation, 1 g/L (Mo)/HRTiO2 degraded ~98% initial 50 mg/L IBU concentration after 80 min 365 nm UV light irradiation under natural (unmodified) pH conditions. Effects condition, catalyst dosage, pollutant were also investigated suspension. test supported removed ~60% 5mg/L concentration, while showing improved with ~90% removal employing double triple numbers coated disk tablets. After three successive cycle runs, XRD phase reflections base TiO2 component layer remained unchanged: An indication surface coat stability 360 exposure irradiation.
