| 中文摘要 | Bismuth oxybromide (BiOBr) was prepared and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and UV-vis diffuse reflectance spectroscopy (DRS). The BiOBr promoted detoxification of cylindrospermopsin (CYN) under UV (lambda < 350 nm) and visible light (lambda > 420 nm) illumination was studied. The results revealed that the toxic uracil unit of CYN was removed, and the carboxylic group of the degraded product was also decomposed, to give the innoxious tricyclic guanidine product under the title conditions. In contrast, the traditional Fenton reagents (Fe2+ and H2O2) limited to remove the uracil moiety of CYN with the carboxylic group intact. Presumably, the decarboxylation ability of BiOBr was induced by Br 4p valence band hole (h(Br) (+)(4p)), and the degradation mechanism was also proposed based on the experimental results and theoretical calculation.
