The hierarchical porous heterostructured MIL‐125/TiO2@SiO2 composites are successfully obtained by biogenic‐templated method using rice husk both as biomorphic. The products are characterized by X‐ray diffraction, N2‐adsorption‐desorption analysis, scanning electron microscopy and Fourier transform infrared spectroscopy. The results reveal that MIL‐125/TiO2@SiO2 possesses a hierarchical porous structure in scale from micrometer to nanometer with high Brunauer–Emmett–Teller (BET) surface area (385.7–902.7 m2 g−1). The photocatalytic mechanism was discussed in detail. Meanwhile, the activity of MIL‐125/TiO2@SiO2 for the photocatalytic degradation of rhodamine B in aqueous medium is significantly higher than that of P25. The current work provides some concept and methods in the development of MOF‐based photocatalysts.
