Abstract

In present study, TiO2 nanoparticles was modified by the addition of CeO2 to increase efficiency and improve catalytic activity under visible light, ultrasonic irradiation, and combination of both irradiation. The as-prepared CeO2 nanoparticles have been incorporated to mixture of TiO2 with various molar ratio (x)TiO2:(1-x)CeO2 = 0.25:0.75; 0.5:0.5 and 0.75:0.25). Then the pristine TiO2, CeO2 and TiO2/CeO2 nanocomposites were identified by X-ray Diffraction (XRD) and the surface area was measured using Brunner-Emett teller (BET) measurement. The XRD results indicated that the CeO2 was a face centered cubic structure and the TiO2 was anatas structures. The as-prepared samples exhibit a good catalytic for the decolorization of methylene blue (MB) under visible light, ultrasonic irradiation, and combination of visible light and ultrasonic irradiation. The enhanced performance might be due to the lower recombination of charge carriers and surface properties of TiO2/CeO2. To further studies the catalytic mechanism the scavenger and initial solution experiment were also tested. Moreover, TiO2/CeO2 nanocomposites shows good cycle stability toward continuous four cycles runs of catalytic experiment for the degradation of MB.
