本项目利用MOFs的可设计思想，引入Keggin型多酸进入体系，进一步构筑新型二维或三维POMs-MOFs的聚合物，发挥其二则的优点。采用有序自组装的合成方法，获得可控的目标结构，是本项目的重点研究内容。同时研究POMs-MOFs体系对不同染料的光催化降解效率，以优化筛选出高效的POMs-MOFs框架化合物。由于POMs-MOFs的聚合物中POMs的氧化还原性质和光催化性质，可通过实验和理论计算进一步研究POMs-MOFs在水体系中对染料分子的光催化降解功能及机理，为水体系中有机污染物的消除，提供实验及理论依据。

In this project, we will design and synthesize series of novel two-dimension or multi-component POMs-MOFs by introducing Keggin-polyoxometalates (Keggin-POMs) anions based on the highly designable MOFs. Meanwhile, the project will mostly concentrate on well-ordered self-assembly synthetic method to achieve target structure. Furthermore, the photocatalytic degradation efficiency of POMs-MOFs system for different dyes was investigated in order to optimize the POMs-MOFs. According to POMs special properties in POMs-MOFs systems that exhibit rich redox and photoactivity, we will research in the potential applications in degradation of dye molecules, and study the function and mechanism of photocatalytic degradation of POMs-MOFs in the water system through experiments and theoretical calculations, which provide experimental and theoretical evidence for the elimination of organic dyes.
