MOFs材料在分离膜中的应用

Application of MOFs in separation membranes

MOFs材料具有骨架构型可设计性强,比表面积大,孔隙率高、化学性质、热学性质易调等特点,因此在吸附、传感器、催化以及分离等领域引起人们广泛关注。在简要介绍MOFs材料及其分离膜制备方法的基础上,分析了MOFs对膜分离性能的影响因素如表面官能团、粒径、形貌、孔径、用量及其它次级效应等,并对今后的研究方向提出建议。

Due to its superior characteristics,such as tailoring framework structure,high specific area,high porosity,adjustable chemical and thermal properties,metal-organic frameworks(MOFs)have attracted much attention in the areas of absorption,sensors,catalyst and separation,etc.Based on the introduction of preparation methods for MOFs and membranes containing MOFs,in the paper,the effects of MOFs,such as functional group,particle size,morphology,pore size,dosage and other influence factors on the performances of the membranes were emphasized.The future research trends of the MOFs membrane were also suggested.
