Due to their persistent and pervasive distribution and their adverse effects on human health, the removal of per- and polyfluoroalkyl substances (PFAS) from the environment has been the focus of current research. Recent studies have shown that engineered nanomaterials provide great opportunities for their removal by chemical, physical and electrochemical adsorption methods, or as photo- or electrocatalysts that promote their degradation. This review summarizes and discusses the performance of recently reported nanomaterials towards PFAS removal in water treatment applications. We discuss the performance, mechanisms, and PFAS removal conditions of a variety of nanomaterials, including carbon-based, non-metal, single-metal, and multi-metal nanomaterials. We show that nanotechnology provides significant opportunities for PFAS remediation and further nanomaterial development can provide solutions for the removal of PFAS from the environment. We also provide an overview of the current challenges.
由于其持久性和普遍存在的分布，以及对人类健康的不利影响，从环境中去除全氟和多氟烷基物质（PFAS）一直是当前研究的重点。最近的研究表明，工程纳米材料通过化学、物理和电化学吸附方法，或作为光或电催化剂来促进其降解，为它们的去除提供了很大的机会。本综述总结和讨论了最近报道的纳米材料在水处理应用中去除 PFAS 的性能。我们讨论了各种纳米材料（包括碳基、非金属、单金属和多金属纳米材料）的性能、机制和 PFAS 去除条件。我们表明，纳米技术为 PFAS 的修复提供了重要的机会，进一步的纳米材料开发可以为从环境中去除 PFAS 提供解决方案。我们还概述了当前的挑战。
