Abstract: |
The Microemulsion method was successfully used to prepare a series of TiO2, iron oxide and SiO2 doped TiO2 nanoparticles at a doping level of 5 at. %. The molar ratio of water to surfactant W0 (= [water]/ [Surfactant]) was 2 and the samples were calcined at 350°C. The structural features of parent TiO2, Fe oxide-TiO2 and SiO2-TiO2 have been investigated by XRD, UV-Visible, SEM and TEM. The data indicated that in comparison with pure TiO2 sample, the iron oxide and SiO2 doped TiO2 samples had relatively large particle size indicating that the doping with Fe oxide and SiO2 can increase the particle size. Among all the samples, pure TiO2, Fe oxide and SiO2 doped TiO2, Fe oxide–TiO2 sample showed the highest activity on the photocatalytic decomposition of methylene blue. |
