Recently, organic dyes in wastewater has become a threat to the ecosystem and human health. The synthesis of high-performance and recyclable photocatalysts still remains a challenge. The photoreduction efficiency of rhodamine B (Rh B) is hindered by the high rate of recombination of electron-hole pairs and the low adsorption of Rh B. In this work, bismuth oxybromide (BiOBr) and single walled carbon nanotubes (SWCNT) composites were prepared via a facile method and applied to the reduction of Rh B. The chemical state of the elements, microstructure, surface elements, and optical properties of the BiOBr/SWCNT were characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photo electron spectroscopy (XPS), and UV-Vis diffuse reflectance spectroscopy. |
