Abstract:

Compared with single MOFs, MOFs@aerogels have ultra-high specific surface area, high porosity, good polymer compatibility and excellent structural pores, which can efficiently adsorb and remove pollutants in water. This paper introduced the structure and physicochemical properties of MOFs@aerogels, as well as the commonly used synthesis strategies of MOFs@aerogels. The advantages and disadvantages of the synthesis strategies and the challenges were analyzed. The adsorption conditions and adsorption properties of MOFs@aerogels for heavy metal ions and organic compounds in wastewater were described in detail, and the related adsorption mechanisms were systematically summarized and compared. The reusability of MOFs@aerogels in adsorption of pollutants was described. Finally, the optimization direction of the stability of MOFs in MOFs@aerogels, the matrix materials of aerogels, the application range and drying technology were proposed. It was proposed that improving the stability of MOFs@aerogels, exploring new matrix materials, expanding the application range of MOFs@aerogels, and exploring economical and green synthesis technologies would be the future research directions.
