摘要: Copper bismuthate (CuBi2O4) complex oxides with a variety of novel morphologies have been prepared via a low-temperature solution process. The structure, morphology and light absorption properties were characterized with XRD, SEM, TEM and UV-vis diffuse reflectance. The effects of synthetic conditions (treatment time, additives and KOH concentration) on the morphology have been discussed, and the photocatalytic properties under UV-visible light irradiation were also evaluated using a degradation experiment. The results showed that the prepared samples exhibited some novel morphologies, such as assembly nanorods, leaf-like nanosheets and hierarchical nanoflowers, and excellent visible light absorption properties. Evident degradation for methylene blue was also observed in the range of UV-visible light irradiation with the help of a trace amount of hydrogen peroxide and their photocatalytic properties exhibited a strong dependence on morphology. Additionally, the photocatalytic mechanism was also illuminated.
