Synthesis of Magnetic Fe₃O₄@TiO₂ Nanocomposite and its Photocatalytic Property

Abstract:

A facile hydrothermal method has been developed for synthesis of nanocapsual-shaped α-Fe₂O₃ using FeCl₃•6H₂O as iron source, 4, 4–bipyridine and thiourea as surfactant, and then the above α-Fe₂O₃ sample’s outer surface were coated with TiO₂ and obtained nanocomposite of α-Fe₂O₃@TiO₂. Magnetic nanocomposite (Fe₃O₄@ TiO₂) were obtained by a reduction process with the above α-Fe₂O₃@ TiO₂ products as starting materials by hydrothermal synthesis method using hydrazine hydrate as reductant. The as-prepared Fe₃O₄@TiO₂ samples have good photocatalytic activity and it can photocatalyze RhB at the condition of the external magnetic field
