The Mn-doped bismuth oxide bromide (BiOBr) microspheres have been prepared by hydrothermal method. The resultant composite microspheres exhibited higher photocatalytic activity under visible light irradiation, attributing to the improvement of the photo-absorption property and the separation efficiency of photogenerated electrons and holes. The holes and O2?? are the main active species in aqueous solution under visible light irradiation, rather than ?OH.
