Preparation BiTaO₄ by Precipitation Method and its Visible-Light Photocatalytic Activity

Abstract:

The single phase BiTaO₄ was synthesized using Ta₂O₅ and Bi(NO₃)₃ as main raw materials by precipitation process. The products were characterized by thermogravimetry and differential thermal analysis (TG-DTA), powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-visible diffuse reflectance spectroscopy (DRS). The results show that BiTaO₄ was triclinic crystal with average particle size 100nm, and a band gap of about 2.77 eV. The photocatalytic experiment of BiTaO₄ shows the good photocatalytic activity for the decomposition of methylene blue under visible-light irradiation.
