摘要

调控金属-有机骨架（MOF）结构以增强全氟烷基和多氟烷基物质的去除仍然是一项重大挑战。本文采用拓扑调节策略，合成了两种由相同无机和有机组分组成的zr - mof，并研究了它们对全氟辛酸（PFOA）的去除效率。合成的Zr-MOF-1具有sqc结构，其对PFOA的吸收能力是具有scu结构的Zr-MOF-2的近5倍。Zr-MOF-1对PFOA的吸附量达到335.4 mg/g，吸附机理为化学吸附和物理吸附的协同作用。本研究阐明了结构框架对吸声性能的精确调节。

Topology-Regulated Zirconium Metal–Organic Frameworks for Enhanced Removal of Perfluorinated Pollutants

The regulation of metal–organic framework (MOF) structures for the enhanced removal of perfluoroalkyl and polyfluoroalkyl substances remains a significant challenge. Herein, employing a topology regulation strategy, we synthesized two Zr-MOFs composed of identical inorganic and organic components and investigated their removal efficiency with perfluorooctanoic acid (PFOA). The resultant Zr-MOF-1, characterized by the sqc topology, demonstrated an absorption capacity for PFOA nearly five times greater than that of Zr-MOF-2, which featured the scu topology. The adsorption capacity of Zr-MOF-1 for PFOA reached 335.4 mg/g, attributed to a synergistic mechanism encompassing both chemical and physical absorption. This study illuminates the precise regulation of the absorption performance by structural frameworks.
