This work demonstrated a facile and swift surfactant-free solvothermal synthesis of BiOBr architectures at 170°C for 6h. The structure and morphology were probed through diverse microscopy apparatus. The XRD result shows the obtained samples were well-crystallized tetragonal phase of BiOBr architecture. SEM images display these microspheres were distributed with a good polydispersity, even though most of them have inconsistent diameters. UV-vis spectrum reveals the band gap energy is approximately about 2.87 eV. The PL spectrum of the obtained BiOBr tested at room atmosphere reveals the strongest emission peaks appear at 469nm, which is in the visible region. On the basis of the above results, BiOBr samples also exhibit excellent photocatalytic performance in decomposing the organic dye RhB, which degradation efficiency reaches 99.7% after 50 min under ultraviolet light irradiation.
