Photocatalytic decolorization of dye wastewater containing congo red with carbon nanotube/BiOBr composite photocatalyst
摘要
Abstract
The composite photocatalyst carbon nanotube/BiOBr (MWCNTs/BiOBr) was prepared by hydro⁃thermal method using multi- wal ed carbon nanotubes (MWCNTs), KBr and Bi(NO3)3·5H2O as raw materials. The photocatalytic activity of the photocatalyst under xenon lamp was studied using congo red as the target pol utant. The effects of photocatalyst dosage, congo red initial concentration, anion species on the decoloriza⁃tion of congo red were investigated and the stability of photocatalyst was also verified. The results showed that the introduction of carbon nanotubes could make the photocatalytic activity and adsorption performance of the MWCNTs/BiOBr composite significantly better than BiOBr. The decolorization was as high as 99%when catalyst dosage was 1.5 g/L , the initial concentration of congo red was 15 mg/L, and the photocatalytic time was 120 min. The main active species in the reaction system were hole (h+) and hydroxide radical (·OH). The decolorization of congo red could stil reach more than 92%after 4 repeated cycle use.关键词
