Abstract

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) pollution with their toxicity, carcinogenicity, and persistence has been concerned worldwide. Research into novel materials for detecting and removing PFASs has increased rapidly, particularly in regard to the emergence of well-characterized single-atom materials (SAMs). Owing to the high selectivity, high atom utilization, and abundant active sites of SAMs, these materials exhibit remarkable efficacy in the detection and removal of PFASs. In this work, recent advances in the synthesis of SAMs for the detection and removal PFASs are reviewed. In-depth discussions of the structure–activity relationship and reaction mechanisms have demonstrated the high efficiency, activity, and selectivity of SAMs for the detection, adsorption, and degradation of PFASs. To optimize the application of SAMs in PFASs remediation, this review comprehensively surveys SAMs applications for PFASs and analyzes potential design strategies based on synthesis methods and corresponding properties. Synthesis strategies such as wet-chemistry, which offer ease of operation and high potential for large-scale production, are recommended for the further exploration of specific SAMs for the detection and removal of PFASs. Finally, this review identifies the challenges and opportunities for development of SAMs for the detection and remediation of PFASs, providing an outlook on strategic goals for a green economy and sustainable development.

用于检测和去除全氟烷基和多氟烷基物质的单原子材料

全氟烷基和多氟烷基物质（PFASs）污染因其毒性、致癌性和持久性而受到全世界的关注。用于检测和去除PFASs的新型材料的研究迅速增加，特别是关于特性良好的单原子材料（sam）的出现。由于SAMs的高选择性、高原子利用率和丰富的活性位点，这些材料在检测和去除PFASs方面表现出显著的效果。本文综述了近年来用于检测和去除PFASs的sam的合成研究进展。对结构-活性关系和反应机理的深入讨论表明，SAMs在检测、吸附和降解PFASs方面具有高效率、活性和选择性。为了优化SAMs在全氟辛烷修复中的应用，本文综述了SAMs在全氟辛烷修复中的应用，并根据合成方法和相应的性质分析了可能的设计策略。湿化学等合成策略易于操作且具有大规模生产的潜力，被推荐用于进一步探索用于检测和去除PFASs的特定sam。最后，本文指出了发展用于全氟磺酸检测和修复的sam的挑战和机遇，并展望了绿色经济和可持续发展的战略目标。图形抽象
