Preparation of TiO2/Ag[BMIM]Cl Composites and Their Visible Light Photocatalytic Properties for the Degradation of Rhodamine B

In order to degrade toxic pollutants such as dyes during the process of sewage treatment, considerable attention has been paid photocatalytic technologies. this paper, TiO2/Ag[BMIM]Cl (1-butyl-3-methyl imidazolium chloride ([BMIM]Cl)) nanocomposites were prepared with TiO2 carrier, silver ions dopants and ionic liquids (IL) modifiers. The morphologies, microstructures, crystalline structure optical properties nanospheres are investigated by transmission electron microscopy (TEM), X-ray diffraction (XRD), total organic carbon (TOC), UV-vis diffuse reflectance spectrum (UV-vis DRS) techniques. can selectively rhodamine B (Rh B) under visible light because unstable quaternary ammonium salt. as-obtained exhibit better activity performance than pure TiO2, TiO2/IL, TiO2/Ag+. experimental results show that Rh degradation rate reach 98.87% optimized producing conditions using composites catalyzer. It shows simultaneous doping significantly improve in degradation, indicating formation photosensitive AgCl preparation. Ag+ IL addition exchange band gap lengthen wavelength range composite. material advantages low cost, facile preparation reusability excellent effect B.
