Different inorganic/organic photocomposites based on polyoxometalate (POM) nanoparticles have been developed for photocatalytic applications. Currently, polyoxometalate nanoparticles have been successfully in‐situ embedded into an acrylate polymer network by photopolymerization upon mild visible light irradiation at 405 nm. The proposed POM/polymer photocomposites have been characterized using complementary techniques for a better understanding of their photocatalytic activity. Interestingly, the obtained photocomposites exhibit high rigidity, excellent thermal stability, a non‐negligible porosity and new functionalities such as light reactivity and redox properties. Moreover, developed composites showed efficient catalytic activity for the color removal of aqueous solutions of erythrosine and rose Bengal under Light Emitting Diodes LED@375 nm irradiation reaching 80 and 90% as a final color removal, respectively.

多金属氧酸盐/聚合物光复合材料的表征：有机污染物光降解的工具箱

已经开发了基于多金属氧酸盐（POM）纳米颗粒的不同无机/有机光复合材料，用于光催化应用。目前，多金属氧酸盐纳米颗粒已经通过在405 nm的温和可见光照射下进行光聚合成功地原位嵌入丙烯酸酯聚合物网络中。拟议的POM /聚合物光复合材料已使用互补技术进行了表征，以更好地了解其光催化活性。有趣的是，所获得的光复合材料显示出高的刚性，优异的热稳定性，不可忽略的孔隙率以及诸如光反应性和氧化还原特性的新功能。此外，
