【 摘 要 】

Catalyst of Bi2O2CO3and Fe2O3modified Bi2O2CO3(Fe2O3/Bi2O2CO3) were prepared by hydrothermal method and characterized by X-ray diffractions (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM) and UV-vis DRS. The catalytic activity of Bi2O2CO3and Fe2O3/Bi2O2CO3were comparatively investigated in the photodegradation and Fento-like process. Rhodamine B(RhB) was selected as the target pollutant under the irradiation of 300 W xenon lamp. The results indicated that Fe2O3 plays a great role in the enhancing the treatment efficiency and the and the maximum reaction rate was achieved at the Fe2O3loading of 1.5%. The Fenton-like degradation rate constant of RhB with bare Bi2O2CO3in dark is 0.4 min-1, while that with 1.5 Fe2O3/Bi2O2CO3increases to 28.4 min-1under visible light irradiation, a 71-fold improvement. It is expected to shed a new light for the constructing novel composite photocatalyst and also provide a potential method for the removal of dyes in the aqueous system.
