Hierarchical BiOBr microspheres with an average diameter of 1–4 µm were prepared via a one-pot EG-assisted solvothermal process in the presence of a reactable IL. The experimental results indicate that the solvothermal temperature has important effects on the crystallite size, optical properties, adsorption capacity, and photocatalytic activity of BiOBr microspheres. Among all the samples, BiOBr160 showed the best adsorption capacity and photocatalytic activity for RhB degradation under visible

Hierarchical BiOBr microspheres were synthesized via a one-pot solvothermal process in the presence of ethylene glycol and 1-butyl-3-methylimidazolium bromide ([BMIM]Br) as a reactable ionic liquid. The products were characterized by X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, UV-Vis diffuse reflectance absorption spectra, nitrogen adsorption-desorption measurements, and photoluminescence spectroscopy. The photocatalytic activity of BiOBr microspheres was evaluated in terms of the degradation of Rhodamine B...
