چکیده انگلیسی
In this paper, reactive brilliant X-3B was used as a model compound to study the photocatalytic activity of TiO2. Experimental results showed that the adulteration of iron and silver on TiO2 could greatly improve the activity of TiO2, and the optimum adulteration amount of iron and silver was 0.1Â wt.% (Fe/TiO2) and 0.05Â wt.% (Ag/TiO2), respectively, at the adulteration range of experiments. The photocatalytic degradation kinetics of X-3B on TiO2, Fe/TiO2 and Ag/TiO2 were also studied. The results showed that the degradation of X-3B on all of them were in accordance with the Langmiur-Hinshelwood kinetics model well, and the sequence of apparent reaction rate constants k of X-3B degradation catalyzed by TiO2, Fe/TiO2 and Ag/TiO2 was Ag/TiO2Â >Â Fe/TiO2Â >Â TiO2, while adsorption equilibrium constants KA of X-3B on Fe/TiO2 and Ag/TiO2 were approximately the same, and both were greater than that of TiO2.
