Abstract:
Zeolite loaded Fe-doped TiO
2 photocatalysts were prepared by sol-gel method using tetrabutyl titanate and ferric nitrate as raw materials and natural zeolite as carrier. The samples’ structure, crystalline phase and doping element were characterized by XRD, SEM, EDS and XPS. The results showed that TiO
2 existed with anatase form in the photocatalysts calcined at 400 ℃. The doping titanium and iron mainly existed in Fe
2O
3 doped zeolite. The zeolite loaded Fe
2O
3/TiO
2 mainly shows spherical or sphericallike structure. The degradation experiments showed that the photocatalysts had a good degradation performance for methyl orange, also easy be recovered and recycled
