PREPARATION AND CHARACTERIZATION OF DOPEDTTANA NANOPARTICILES: PREPARED) VA VATER-N-OL MCROEMULSON

The Microemulsion method was successfully used to prepare a series of TiO, iron oxide and SiO2 doped TiO2 nanoparticles at a doping level of 5 at. %. The molar ratio of water to surfactant Wo (= water/ Surfactant) was 2 and the samples were calcined at 350°C. The structural features of parent TiO, Fe oxide-TiO, and SiO-TiO, 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 SiO, doped TiO, Fe oxide TiO, sample showed the highest activity on the photocatalytic decomposition of methylene blue.
