Abstract

HZSM-5 was used to support TiO2 photocatalyst through sol gel method. The XRD patterns reveal anatase TiO2 and HZSM 5 in the composites. Crystallite sizes increase apparently with increasing calcination temperature, while there is only a slight increase in crystallite size with increasing calcination time. TiO2 is coated on the surface of zeolite in 50%TiO2 /HZSM5, while the dif ference in calcination temperature ha s very small influence on morphology of the materials. The 50%TiO2 /HZSM5 calcinated at 450 oC for 2 h has the largest surface area of 243.1 m 2 /g and the maximum photocatalytic activity on methyl orange degradation..
