•A novel strategy for in situ synthesis of hybrid Fe3O4/MIL-101 was reported.•Fe3O4/MIL-101 has higher BET surface area and pore volume compared to bare MIL-101.•Fe3O4/MIL-101 can adsorb the anionic dyes quickly and efficiently.•Fe3O4/MIL-101 can be rapidly magnetic separated with desirable durability.
Integration of other functional materials onto the surface or into the matrixes of metal-organic frameworks (MOFs) is an attractive and effective approach to fabricate multifunctional MOFs. Herein, we report a facile and novel strategy for in situ synthesis of magnetic hybrid Fe3O4/MIL-101 via heterogeneous coprecipitation assembly. Characterizations showed that the Fe3O4 nanoparticles were uniformly coated on the outer-surface of MIL-101. The as-synthesized Fe3O4/MIL-101 composite holds larger BET surfaces area, pore volume and higher positive charge than MIL-101. These preferable properties make it to be an excellent candidate for adsorption and removal of anionic dye from aqueous solution. The present work provides a new insight for in situ synthesis of Fe3O4-functionalized MOFs, offering an alternative way to prepare magnetic hybrid materials for a wide range of applications.
