제목 Photocatalytic Decomposition of Rhodamin B under Visible Light Irradiation over Metal-Doped TiO2 Prepared Using Two-Phase Method
초록 In this paper, we have synthesized TiO2 elongated rhombic modification and doped transition metal ions (Ce, Cr and Fe). The samples were characterized using X-ray diffraction (XRD), DRS, PL spectra, TEM and Raman in order to determine the nature of the metal species. In addition, their activity as photocatalysts for the decomposition of Rhodamine B (RhB) was investigated. No crystalline phase containing cerium or cerium oxide peaks were detected in the Ce-doped TiO2 materials similar to those for the Fe-doped TiO2 material and the Cr-doped TiO2 material. . From the TEM images of bare and metal-doped TiO2 samples prepared according to the procedure described above. Well-crystallized elongated rhombic-like particles with uniform size are obtained.
