Adsorption and Photocatalytic Degradation of Active Brilliant Red X-3B on the Mixture of TiO₂ and HZSM-5

Abstract:

A mixture of TiO2 and HZSM-5 zeolite was used for adsorption and photocatalytic degradation of an azo dye, Active Brilliant Red X-3B. ABR X-3B adsorption on HZSM-5 zeolite is quite small although the amount of HZSM-5 is as many as 0.5 g/l. Photocatalytic degradation of ABR X-3B on HZSM-5 is less than 5% after 90 min of irradiation. When the adding amount of HZSM-5 is 300 mg/l, the maximum decoloration rate on the mixture reaches 88.1% that is 22.7% more than that on pure TiO2. The variations of adsorption and photocatalytic degradation on the mixture are not large with changing of HZSM-5 amount from 0.05 g to 0.6 g.
