Hierarchical BiOBr microspheres with oxygen vacancies, which can be used for the dyes removal, have been synthesized successfully in the presence of different kinds of ionic liquids. It was revealed that BiOBr prepared by the ionic liquids with short chain length exhibited higher photocatalytic activity in the degradation of methyl orange (MO) under visible light. The experimental results showed that the phenomenon of the photocatalytic degradation of MO can be explained by the photoluminescence spectra.
Graphical abstractHierarchical BiOBr microspheres can be applied for the removal of methyl orange under visible light. When the BiOBr samples are irradiated by visible light, the electrons in the VB can be transferred to CB whereas holes are appeared in VB at the same time. As a conclusion, methyl orange can be degraded to CO2 and H2O, as well as other salts, which are environmental-friendly.Figure optionsDownload full-size imageDownload as PowerPoint slide
