Metals Organic Frameworks (MOFs) are promising crystalline, embrittled materials generally produced in powdering form with varied remarkably functionalities. In contrary, polymers are flexible and processable materials. Therefore, obtaining shaped solids gathering polymer malleability and MOFs properties such as their photocatalytic activities, have attracted many researchers’ attention. This work, reports the successful fruitful incorporation of two different Fe‐based MOFs into a polymer matrix via a facile and cheap photopolymerization process upon mild visible light irradiation at 405 nm. The as‐prepared photocomposites display excellent stability and photocatalytic performance for several Acid Black degradation cycles. Hence, approximatively, 95 % of this model dye is decomposed by the two MIL‐100(Fe)/polymer and MIL‐88 A(Fe)/polymer composites under just 30 min of UV‐Visible lamp irradiation. Incorporation of the MOFs into the polymer is confirmed by several techniques including Scanning Electron Microscopy (SEM), Energy‐Dispersive X‐ray analysis (EDX), Transmission Electron Microscopy (TEM), X‐ Ray Diffraction analysis (DRX), Fourier‐Transform Infrared Spectroscopy (FTIR). Furthermore, these photocatalysts exhibit a high thermal stability, excellent rigidity and low band gap energy characterized by Thermogravimetric Analysis (TGA), Atomic Force Microscopy (AFM), Dynamic Mechanical Analysis (DMA) and UV‐Visible diffuse reflectance spectroscopy, respectively.
