dc.description.abstractZSM-5 supported TiO2 photocatalysts were synthesized by P25 TiO2 and sol gel TiO2 methods, tested by photocatalytic degradation of acetophenone in aqueous media, and characterized by XRD. Degradation results demonstrated higher photoactivities of the photocatalysts prepared by P25 method. Thus, these photocatalysts were intensively studied for better understanding the supported TiO2 photocatalyst. TiO2 maximum coverage on ZSM-5 surface was estimated by solid 1H-29Si CP-MAS FT-NMR to be 23% at 2.5 wt% TiO2 loading, which agree well with literature values. Acetophenone isotherm adsorption result reveals a monolayer and a multi-layer adsorptions and the Langmuir isotherm fits well the monolayer region. A maximum monolayer adsorption of 69.0 mg/g photocatalyst was obtained from Langmuir fitting. Based on the acetophenone molecule dimensions, the maximum acetophenone monolayer adsorption, maximum TiO2 coverage, and ZSM-5 zeolite characteristics, a surface model of TiO2/ZSM-5 is developed quantitatively.en
