Fe-doped anatase TiO2 nanobelts were prepared using layered titanate nanobelts as precursor by two-step hydrothermal process. Various measurement techniques were employed to investigate the morphology and structure of products. The results show that Fe-doped TiO2 still remain nanobelt-like and structure as pure TiO2 nanobelts. Fe-cations doped in TiO2 nanobelts lead to the red-shift of the absorption edge of TiO2 nanobelts. The visible-light photodegradation of Rhodamine B on the products exhibits that Fe-doped products with low Fe-content show higher photocatalytic activity than that of TiO2 nanobelts or Fe-doped product with high Fe-content.
