Solid photocatalysts with high specific surface area, superior photoactivity and ease of recycling are highly desired in chemical process, water treatment and so on. In this study, a facile stepwise sol-gel coating approach was utilized to synthesize Pt decorated oxygen-deficient mesoporous titania microspheres with core-shell structure and convenient magnetic separability (denoted as Fe₃O₄@SiO₂@Pt/mTiO_2-x). These photocatalysts consist of magnetic Fe₃O₄ cores, nonporous insulating SiO₂ middle layer and mesoporous anatase TiO_2-x shell decorated by Pt nanoparticles (~3.5 nm) through wet impregnation and H₂ reduction. As a result of high activity of oxygen-deficiency of black TiO_2-x by H₂ reduction and efficient inhibition of electron-hole recombination by Pt nanoparticles, the rationally designed core-shell Fe₃O₄@SiO₂@Pt/mTiO_2-x photocatalysts exhibit superior photocatalytic performance in rhodamine B (RhB) degradation under visible light irradiation, with more than 98% of RhB degraded within 50 min. These core-shell structured photocatalysts show excellent recyclability under the assistance of magnetic separation with well-retained photocatalytic performance even after running five cycles. This stepwise synthesis method paves the way for the rational design of a high-efficiency recyclable heterogeneous catalyst, including photocatalysts, for various applications.
