Abstract

Novel BiVO₄/Bi₂S₃ heterostructures were fabricated simply by growing Bi₂S₃ nanoribbons on the surface of BiVO₄ nanoscrolls, in situ, using pre-synthesized BiVO₄ and bismuth(III) dimethyldithiocarbamate (Bi(dedc)₃) as precursors. The length and density of the anchored Bi₂S₃ nanoribbons were controlled by tuning the amount of Bi(dedc)₃ reacted with BiVO₄ nanoscrolls. Compared to pure BiVO₄, the prepared BiVO₄/Bi₂S₃ heterostructures showed enhanced photocatalytic activity for Cr(VI) reduction under UV-visible light illumination, mainly due to the extended range of visible light absorption and the improved separation efficiency of photoinduced electrons and holes.
