Abstract

Core–shell structure ${Fe@TiO}_{2}$ was synthesized by sol–gel method. The photocatalytic degradation of methylene blue over the ${Fe@TiO}_{2}$ reached 98% under UV light irradiation within 5 h. The band gap of the core–shell ${Fe@TiO}_{2}$ was found to have a redshift through a sintering treatment. The redshifted ${Fe@TiO}_{2}$ had a good performance of methylene-blue degradation (reaching 85%) under visible light irradiation for 5 h.
