摘要: 通过水热法制备了Bi25FeO40及Bi25FeO40/GO。利用SEM、XRD、TEM、UV-vis等手段对所制备的材料进行了表征。以罗丹明B模拟废水染料,对制备的材料进行了光催化性能测试。实验结果表明,Bi25FeO40/GO比Bi25FeO40具有更好的光芬顿催化性能,这是因为GO的掺入增加了复合物对罗丹明B的吸附量,并增加了光电子传输效率,提高了其催化性能。在120 min内,Bi25FeO40/GO对30 mg·L-1的罗丹明B去除率达到95%。

Abstract: Bi25FeO40 and Bi25FeO40/GO were prepared by hydrothermal method. The repared materials were characterized by SEM, XRD, TEM and UV-vis.The photocatalytic performance of the prepared materials were tested by degradating RhB dye wastewater. The experimental results showed that Bi25FeO40/GO had better photocatalytic performance than Bi25-FeO40.The incorporation of GO increased the adsorption capacity of the composite to RhB, and increased the photoelectron transport efficiency, thereby improving the catalytic performance. The removal rate of rhodamine B of 30 mg·L-1 reached 95% in 120 min.

Key words: barium ferrite; hydrothermal; graphene oxid; photo-Fenton
