Abstract：

The　magnetic　TiO2-Fe3O4/MIL(Material　Institute　Lavoisier)-101(Cr)　composites　were　synthesized　via　in　situ　hydrothermal　method.　The　structure　and　performance　of　composites　were　characterized　by　XRD,　SEM,　UV-Vis　DRS,　BET　and　superconducting　magnet　system.　The　photocatalytic　activity　of　TiO2-Fe3O4/MIL-101(Cr)　composites　were　investigated　by　photocatalytic　degradation　of　MB　solution,　and　the　stability　of　TiO2-Fe3O4/MIL-101(Cr)　composites　was　also　studied.　The　results　show　that　the　thiohydroxy-modified-Fe3O4　and　thiohydroxy-modified-TiO2,　can　be　successfully　combined　with　MIL-101(Cr),　and　a　notable　absorption　extension　in　the　visible-light　region　can　be　observed　for　the　TiO2-Fe3O4/MIL-101(Cr)　composites.　The　TiO2-Fe3O4/MIL-101(Cr)(400)　composite　exhibits　the　highest　photocatalytic　activity,　while　the　corresponding　photodegradation　efficiency　for　MB　is　80%　after　120　min　irradiation.　The　TiO2-Fe3O4/MIL-101(Cr)　composites　also　have　a　good　stability　and　can　be　easily　separated　from　solution　by　an　external　magnet.　©　2017,Chinese　Society　for　Composite　Materials.　All　right　reserved.
