Per- and polyfluoroalkyl substances (PFAS) are a group of recalcitrant molecules that have been used since the 1940s in a variety of applications. They are now linked to a host of negative health outcomes and are extremely resistant to degradation under environmental conditions. Currently, membrane technologies or adsorbents are used to remediate contaminated water. These techniques are either inefficient at capturing smaller PFAS molecules, have high energy demands, or result in concentrated waste that must be incinerated at high temperatures. This Review focuses on what role metal-organic frameworks (MOFs) may play in addressing the PFAS problem. Specifically, how the unique properties of MOFs such as their well-defined pore sizes, ultra-high internal surface area, and tunable surface chemistry may be a sustainable solution for PFAS contamination.
全氟和多氟烷基物质 (PFAS) 是一组难降解的分子，自 20 世纪 40 年代以来已在各种应用中使用。它们现在与许多负面的健康结果有关，并且在环境条件下极难降解。目前，膜技术或吸附剂用于修复受污染的水。这些技术要么对捕获较小的 PFAS 分子效率不高，要么能耗高，要么产生必须在高温下焚烧的浓缩废物。本综述重点介绍金属-有机骨架 (MOF) 在解决 PFAS 问题方面可能发挥的作用。具体来说，MOFs 的独特性质，如其明确的孔径、超高的内表面积和可调节的表面化学性质，如何可能成为 PFAS 污染的可持续解决方案。
