Environmental pollution has drawn forth advanced materials and progressive techniques concentrating on sustainable development. Metal-organic frameworks (MOFs) have aroused vast interest resulting from their excellent property in structure and function. Conversely, powdery MOFs in highly crystalline follow with fragility, poor processability and recoverability. Aerogels distinguished by the unique three-dimensional (3D) interconnected pore structures with high porosity and accessible surface area are promising carriers for MOFs. Given these, combining MOFs with aerogels at molecule level to obtain advanced composites is excepted to further enhance their performance with higher practicability. Herein, we focus on the latest studies on the MOFs@aerogel composites. The construction of MOFs@aerogel with different synthetic routes and drying methods are discussed. To explore the connection between structure and performance, pore structure engineering and quantitation of MOFs content are outlined. Furthermore, various types of MOFs@aerogel composites and their carbonized derivatives are reviewed, as well as the applications of MOFs@aerogel for environmental remediation referring to water purification and air clearing. More importantly, outlooks towards these emerging advanced composites have been presented from the perspective of practical application and future development.
环境污染促使人们研发先进材料和进步技术以实现可持续发展。金属有机框架（MOFs）因其结构和功能上的优异性能而引起了广泛的关注。然而，高结晶度的粉末 MOFs 具有易碎、加工性和可回收性差等缺点。气凝胶具有独特的三维（3D）互联孔结构、高孔隙率和可及表面积，是 MOFs 的理想载体。因此，将 MOFs 与气凝胶在分子水平上结合以获得先进复合材料有望进一步提高其性能，具有更高的实用性。本文重点介绍了 MOFs@aerogel 复合材料的最新研究进展。讨论了不同合成路线和干燥方法构建 MOFs@aerogel。为了探索结构与性能之间的关系，概述了孔结构工程和 MOFs 含量的定量。此外，综述了各种类型的 MOFs@aerogel 复合材料及其碳化衍生物，以及 MOFs@aerogel 在水净化和空气净化等环境修复方面的应用。更重要的是，从实际应用和未来发展的角度对这些新兴先进复合材料进行了展望。
