Abstract

Semiconductor nanometer material α-Fe2O3 has been prepared by homogeneous precipitation method. Its microstructure and morphology are analyzed by XRD, TEM. The active brilliant blue K-NR and active dye BRN are degraded by α-Fe2O3. The influence of roasting temperature and dosage of photocatalyst and illumination on the efficiency of photocatalytic degradation is studied. The results of photocatalytic degradation are analyzed by TR and UV. The results reveal that α-Fe2O3 has very high photocatalytic activity to active brilliant blue K-NR and active dye B-RN. The condition is that photocatalyst has seasonable dosage and is roasted at 350 ℃. UV light is used in photocatalytic degradation.
