SYNTHESIS AND OPTICAL PROPERTY CHARACTERIZATION OF METAL ION AND HETERO ATOM DOPED TiO2 NANOCOMPOSITE FABRICATION FOR PHOTO CATALYSIS

Abstract

The transition metal ions and heteroatoms such as iron cobalt and nickel modified titania were synthesized by insitu precipitation and hydrothermal technique. Prepared materials are further treated by thermal analysis towards crystalline phase formation. The particle size of prepared titania calculated from intense d-space values of prepared materials and it is found to be 22-23 nm. Raman spectra and the DR UV-Visible spectra of metal ion and nitrogen doped titania extends to the visible region (450-650 nm). Methylene blue (MB) dye degradation was performed to evaluate the photosensitivity property of the as prepared materials under sun light irradiation. Metal ion modified titania (0.01Fe- TiO2, 0.01CoTiO2 and 0.01Ni-TiO2) materials are showing complete degradation of MB. For the comparison purpose, the powder nanotitania samples are prepared and also coated on ITO (indium tin oxide) plates by electrodeposition method. XRD and DRS properties of coated titania were tested for electrode application.

Environmentally benign synthesis of TiO2-ZnO nanocomposite for efficient dye-sensitized solar cell

“…The composite semiconductor oxides were also helping to create composite networks with better characteristics. Transition metals including nickel, copper, lanthanum, and vanadium have been doped into TiO 2 to increase its photovoltaic performance and catalysis [25][26][27][28][29]. Nevertheless, substantial research has been done on the combination of TiO 2 and ZnO in the past.…”
