Popis: | International audience; Metals Organic Frameworks (MOFs) are promising crystalline, embrittled materials generally produced in powdering form with varied remarkably functionalities. In contrary, polymer are flexible and processable materials. Therefore, obtaining shaped solids gathering polymer malleability and MOFs properties such as their photocatalytic activities, have attracked many reasearchers attention. This work, report 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 displayed excellent stability and photocalytic performance for several Acid Black degradation cycles. Hence, approximatively, 95% of this model dye was decomposed by the two MIL-100(Fe)/polymer and MIL-88A(Fe)/polymer composites under juste 30 min of UV lamp irradiation. Incorporation of the MOFs into the polymer was confirmed by several techniques including Scanning Electron Microscopy (SEM), Energy-dispersive X-ray analysis 2 (EDX), Transmission Electron Microscopy (TEM), X-Ray Diffraction analysis (DRX), Fourier-Transform Infrared Spectroscopy (FTIR). Furthermore, these photocatalysts exhibited 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. |
