Photocatalytic performance of Mg-doped TiO2 nanoparticle for photocatalyticdegradation of some environmental pollutants under UV light in aqueoussolution

In this research Mg-doped TiO2 nanopowders were synthesized by the sol–gel method. The Mg-TiO2 photo-catalyst was prepared using Titanium tetra-iso propoxide and Magnesium sulfate asthe dopant precursors. Rhodamine B, Nonylphenol ethoxylates 6 mol, Pseudoephedrinehydrochlorid, and Nicotine were used to study the photocatalytic performance of the Mg dopedTiO2 under UV irradiation. The synthesized samples were characterized by x-ray diffraction, xrayphotoelectron spectroscopy, Transmission electron microscopy (TEM), X-ray photoelectronspectroscopy (XPS) and Photoluminescence (PL). The photocataltic degradation show that after60, 90, 120, and 120 of irradiation time with UV light, 99%, 98%, 98% and 98% of rhodamine B,Nonylphenol ethoxylates 6 mol, Pseudoephedrine hydrochloride, and Nicotine were decomposedby Mg-doped TiO2 sample, respectivly.
