In this study, three-dimensional flower-like Fe-Bi(OH)3 was firstly prepared by using sol-gel
method. The synthesized Fe-Bi(OH)3 was characterized by UV–vis spectrophotometer, scanning
electron microscopy, energy disperse spectroscopy and X-ray powder diffraction. In addition, the
prepared Fe-Bi(OH)3 has been systematically studied as a nano photocatalyst for the degrdndegradation
of Rhodamine B firstly. The results showed that the degradation rate of Fe-Bi(OH)3 was
99.61% under natural daylight. Besides, the degradation efficiency of Rhodamine B can be significantly
improved under red light irradiation. Therefore, Fe-Bi(OH)3 nanocomposites can be
used as a photocatalyst to treat Rhodamine B in industrial wastewater.
