Photocatalytic Degradation of Methyl Orange on Y Zeolite Supported TiO₂

Abstract:

The photocatalytic activity of TiO2/Y photocatalyst was investigated. The experimental results showed that the activity of TiO2/Y photocatalyst prepared by sol-gel method was greatly affected by calcination temperature and the nature of Y-zeolite. Photocatalytic degradation efficiency increased with increasing content of TiO2 on NaY zeolite and reached its maximum rate of 12.4% when TiO2 content was 90%. When TiO2 content was in the range of 50% to 90% , the activity of TiO2/HY was better than pure TiO2. The activity of TiO2/FeY was comparatively low in the TiO2 content range of 50-90%. The enhancement of photocatalytic activity of TiO2 after loading on Y zeolite is not appreciable, indicating that Y type zeolite is not a promising support for TiO2 prepared by sol-gel method.
