Efficient visible-light-induced photocatalytic activity over the novel Ti-doped BiOBr microspheres
A novel and efficient visible-light-induced Ti-doped BiOBr photocatalyst was successfully obtained by double self-assemble method. The resultant samples were characterized by XRD, FE-SEM, HR-TEM, EDS. and UV-vis adsorption spectra. The possible formation process of the as-prepared samples and titanium doping in the lattice of BiOBr were investigated in this paper. The Ti-doped BiOBr microspheres exhibited higher visible-light-induced photocatalytic activity for the degradation of rhodamine B (RhB) than BiOBr due to the synergetic effect of the unique structure and the titanium doping as well as larger specific surface area, which effectively improved photogenerated electrons and holes transferring.
