Abstract
In this paper, the growth of BiOBr cluster spheres on Fluorine-doped Tin Oxide (FTO) substrates was achieved by ethanol dispersion of BiOBr powder and subsequent roasting treatment. After ultraviolet (UV) illumination for 30 min, the BiOBr/FTO composite film could degrade 68 % of 10 mg/L rhodamine B (RhB), which was 36 % higher than that realized by BiOBr powder. The good photocatalytic stability of the composite film was maintained after three cycles. This study revealed the advantages of photocatalytic efficiency enhancement and easy integration of photocatalytic reactors brought about by the thin-film composite of FTO and cluster spheres BiOBr and provided a promising solution for photocatalysts.
