Synthesis and Photocatalytic Properties of Fe-Doped TiO₂ Nanobelts

Abstract:

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.
