摘要：
Bi/TiO2 powder had been prepared in acidity condition at low temperature by the method of ultrasonic deposition. The characteristics of TiO2 and Bi/TiO2 were carried out using XPS, XRD and TEM. The results showed that the band gap is narrower, the TiO2 synthesized belonged to anatase (82.7%) and rutile (17.3%) and the size of Bi/TiO2 was 25.8 nm. The degradation of Sulforhodamine-B(SRB) and 2, 4-dichlorophenol(2, 4-DCP) was used as probe reaction. The changes of TOC values before and after had been measured during the photo-catalytic degradation of SRB under visible light irradiation. The results showed the TOC removal rate of SRB is 61.6%. Photo-catalytic degradation involved in ·OH through detecting oxidation species and catalyst prepared had high activity of catalysis and oxidation.
