摘要：

The preparation, characterization and photoreactivity of heteropolytungstic acid (H3PW12O40)-encapsulated into the titanium-exchanged HY (TiHY) zeolite is presented. In the photoreaction study of methyl orange in the presence of HPA-encapsulated TiO2 zeolite, a 20-fold increase in the photoreaction rate is observed as compared to the rate observed in the presence of HPA-encapsulated HY zeolite without TiO2.
