Visible-Light-Induced Photocatalytic Activity of Boron-Doped BiVO₄

Abstract:

Boron-BiVO₄ samples were synthesized by sol-gel method. They were characterized by UV-vis diffuse reflectance spectroscopy, X-ray diffraction. Photocatalytic activity of the obtained BiVO₄ samples was investigated through degrading methylene blue (MB). The results reveal that boron-BiVO₄ catalysts have monoclinic scheelite structure. The BiVO₄ and Co-BiVO₄ photocatalysts were responsive to visible light. Co-BiVO₄ photocatalyst showed higher photocatalytic activity than pure BiVO₄, resulting in the significantly improved efficiency of degradation of MB.
