Crystalline Bi25FeO40 Cluster Microspheres as Efficient Photo-Fenton Catalysts for Rhodamine B Degradation

In this study, cluster microspheres Bi25FeO40 materials were synthesized by a simple method. The characteristic of the obtained products was studied using the X-ray diffraction (XRD), (FESEM) scanning electron microscopy, UV-vis reflectance. Results showed as-prepared products are uniform microspheres with high porosity, which are composed of aggregation nanocrystal speces into an ordered arrangement structure. Their photocatalytic activity in photodegradation of Rhodamine B under visible light was sequentially investigated, indicating the high photocatalytic capacity of as-obtained the cluster Bi25FeO40 materials.
