Core–shell structure ${\mathrm{\text{Fe@TiO}}}_2$ was synthesized by sol–gel method. The photocatalytic degradation of methylene blue over the ${\mathrm{\text{Fe@TiO}}}_2$ reached 98% under UV light irradiation within 5 h. The band gap of the core–shell ${\mathrm{\text{Fe@TiO}}}_2$ was found to have a redshift through a sintering treatment. The redshifted ${\mathrm{\text{Fe@TiO}}}_2$ had a good performance of methylene-blue degradation (reaching 85%) under visible light irradiation for 5 h.
