Preparation of titanium dioxide/carbon nanotubes/chitosan film and its performance in benzene degradation

Zou Lihui Zhang Quan Zeng Liping Zhang Guoqiang(College of Civil Engineering,Hunan University,Changsha 410082,China)  
The preparation for the photocatalytic material of titanium dioxide /carbon nanotubes/ chitosan film and its performance to remove benzene were studied.First,nanocomposite titanium dioxide /carbon nanotubes was made through sol-gel method,then chitosan was used as crosslinking agent to prepare the titanium dioxide /carbon nanotubes/chitosan film.The film,of which composition,structure,morphology and the absorption performance of light was analyzed by fourier infrared spectroscopy(FT-IR),X-ray diffraction(XRD),transmission electron microscopy(TEM)and UV-Visible diffuse(UV-Vis),was used to remove indoor benzene pollutant,and the comparison was carried out with the catalyst titanium dioxide(P25)/chitosan under the same experimental condition.The result showed that titanium dioxide /carbon nanotubes/chitosan had the better adsorption capacity of benzene and catalytic activity.
