Photocatalytic Activity of TiO2-NaY Composite Photocatalyst on Methyl Orange Degradation

Abstract:

Article Preview

Composite of TiO2 and NaY zeolite was prepared by solid-state dispersion method and the simple mixture of TiO2 and NaY was also compared on methyl orange photocatalytic degradation. Methyl orange degradation rate increased constantly with the increase of TiO2 concentration from 50 mg/l to 200 mg/l and declined gradually afterwards. When the ratio of TiO2 and NaY zeolite was 1:10, the photocatalytic activity of the mixed catalyst was close to that of pure TiO2. The photocatalytic activity of TiO2-NaY composite in different ratio prepared by solid-state dispersion was lower than that of pure TiO2. The photocatalytic activity of the composite catalyst in the ratio of 1:20 was close to that of pure TiO2. Composite catalyst can deposit much quicker than pure TiO2 after treatment.
