The research objectives of the study are to manufacture nano-TiO2 with doping Fe3+, Ce3+ and La3+ adopting impregnation method, examine the effects of the preparing condition on catalyst performance, and explore the influence of the adding account of metal ions and different ion-combinations on the photocatalytic activity of modified nano-TiO2. The experiment results support the following three conclusions...
The photocatalytic oxidation of methyl orange (MO) on commercial TiO2 nano-particles could be successfully enhanced by simple mechanical mixing with Fe3+ modified ZSM-5 zeolites (FeZSM-5). When a mixture of TiO2 and FeZSM-5 (TiO2:FeZSM-5 ratio=1:5) was added into the solution, methyl orange removal rate was 58.9% after 30 min of irradiation, which increased 22% compared with using TiO2 alone. However,...
The paper produces Nano-TiO2 doped with Fe3+, Ce3+, Cu2+, Ce3+ and La3+ using sol-gel method, examines the effects of their preparation condition on catalyst performance, and then explores the influence of the adding amount of metal ions and different ions combinations on photocatalytic activity of modified Nano-TiO2. The result indicates the optimum condition for preparing doped Nano-TiO2 adopting...
A series of Zn2+ and Eu3+ co-doped TiO2 catalysts were prepared by a modified sol-gel method. The prepared catalysts were characterized by X-ray diffraction (XRD), transmission electron microscopy(TEM) and ultraviolet-visible diffuse reflection spectroscopy(UV-vis DRS). Characteristic results clearly show that all of Zn2+ and Eu3+ co-doped TiO2 samples exclusively consist of primary anatase crystallites,...
