Photocatalytic degradation of azo dye by TiO_2/bentonite nanocomposite

SUN Zhenshi 1, CHEN Yingxu 1, KE Qiang 1, YANG Ye 1, YUAN Jun 2 (1. Department of Environmental Engineering, Zhejiang University, Hangzhou 310029; 2. State Key Laboratory of Si Material Science, Zhejiang University, Hangzhou 310027)  
Titanium dioxide/bentonite nanocomposite prepared by acid-catalyzed sol method was used as a photocatalyst in the reaction of cationic azo dye decomposition in water. The incorporation of TiO 2 was confirmed by powder X-ray diffraction (XRD). The nanocomposite photocatalysts have high photocatalytic activity. The intensity of the 490.5*!nm absorption peak corresponding to the cationic red GTL decreased rapidly during the photolysis process. It also indicated that the —N N— bond of GTL was the most active site for oxidative attack. The photo-activity was greatly dependent on the solution pH, and it was more effective for GTL to be degraded under alkaline and neutral conditions.Results also indicated that the proper addition of hydrogen peroxide could improve the decolorization rate, but excess hydrogen peroxide could quench the formation of ·OH. The proper dose of H 2O 2 was 6 mmol/L.
