摘要

The development of advanced materials and technologies in the field of sustainability is of vital importance for addressing environmental pollution. Covalent organic frameworks (COFs) show great potential in the field of environmental remediation due to their ordered structure, high porosity, low density, large specific surface area, alongside excellent chemical stability. These features position COFs as promising candidates for environmental remediation. However, COFs usually exist in powder form with poor processability and recyclability. To overcome such challenges, the construction of COF-based aerogels with a unique three-dimensional interconnected pore structure and extremely low density is considered an important means to realize their device applications. The research on the development of advanced COF aerogel composites at the molecular level opens up a new way and provides a new choice of multifunctional materials for environmental governance. This review focuses on COF aerogels and systematically summarizes their synthesis methods and development in environmental applications.
