The hybrid structures of metal organic frameworks (MOFs) and nanoparticles may offer the realization of effective photocatalytic materials due to combined benefits of the porous and molecular sieving properties of MOF matrix and the functional characteristics of encapsulated nanoparticles. In this study, cadmium telluride (CdTe) quantum dots (QD) are conjugated with a europium-MOF for the synthesis of a novel nanocomposite material with photocatalytic properties. Successful synthesis of a QD/Eu-MOF nanocomposite was characterized with various spectroscopic and microscopic techniques. This QD/Eu-MOF is found to be an effective catalyst to complete the degradation of Rhodamine 6G dye within 50 min.
金属有机框架（MOF）与纳米颗粒的混合结构可能会实现有效的光催化材料，这是由于MOF基质的多孔和分子筛特性以及封装纳米颗粒的功能特性带来的综合优势。在本研究中，碲化镉（CdTe）量子点（QD）与铕-MOF共轭，用于合成具有光催化性能的新型纳米复合材料。通过各种光谱和显微镜技术对QD/Eu-MOF纳米复合材料的成功合成进行了表征。发现这种QD/Eu-MOF是一种有效的催化剂，可在50分钟内完成罗丹明6G染料的降解。
