Paper Title:
Effect of Transition Metal Ions Dopants on Photocatalytic Properties of Titanium-Baring Blast Furance Slag
  Abstract

Transition metal ions have wider optical absorption than TiO2. They can extend the range of absorption light to visible light, taking titanium-baring blast furance slag(TBBFS) as photocatalytic material with a certain amount of transition metal ions to broaden the scope of its spectral absorption and to improve its photocatalytic properties. The impact of transition metal ions Fe3 +, Zr4 + on photocatalytic properties of TBBFS was studied and their optimal doping was searched. TBBFS was grinded and re-doped with transition metal ions and then roasted to prepare photocatalytic materials, using methylene blue’s degradation rate under condition of UV irradiation to evaluate material properties and then using XRD, SEM and other analytical tools for its material characterization. Results show that: doping of transition metals Fe (NO3)3 and ZrO2 can improve the photocatalytic nature of TBBFS and the best doping amount is 0.5% and 3.0% relatively, and its degradation rate is 69.2% and 73.0% respectively.
