Abstract

Ionic liquids and Bi(NO3)3·5H2O were used as raw materials in different solvents to preparate BiOX at room temperature.The prepared samples were analyzed by X ray powder diffraction,the field emission scanning electron microscopy and UV-Vis absorption spectra.The photocatalytic property of BiOX was investigated using rhodamine B aqueous solution.The results showed that the degradation effect of BiOBr prepared with [C4mim]Br in water at 20℃ for 8h was obvious on rhodamine B.After 2h,the photodegradation rate of BiOBr on rhodamine B was 91.71%.
