  • The composite film of carbon nano-tubes/TiO2/chitosan (CNTs/TiO2/CS) was fabricated and characterized by XRD, SEM, TEM and UV-vis. The photocatalytic degradation ability and mechanism of CNTs/TiO2/CS film on gaseous benzene were investigated. The improved photocatalytic degradation ability was achieved due to the synergy of CNTs, TiO2, and chitosan. The intermediates of the photocatalytic degradation were investigated by FT-IR and GC/MS, of which ethyl acetate and hendecene were two major products and minor intermediate products were acrolein 4-carbonyl-methyl-acetophenone, 12-alkane, 2,4 di tert butylphenol, 21-alkane. According to the analysis data of FT-IR and GC/MS, the photocatalytic degradation mechanism of the composite film was illuminated.
