摘要：The persistent contamination of groundwater and surface water by perfluorooctanoic acid (PFOA) has emerged as an urgent environmental issue. Consequently, the development of low-cost, simple-synthesis and high-performance adsorbents to properly remove PFOA distributed in water systems has gained a lot of attention from researchers worldwide. High-nuclear Zr-oxo clusters and chains are rarely explored yet potential candidates to trap PFOA, due to the presence of rich μ3 and terminal hydroxyl. Herein, we demonstrate that the discrete Zr-oxo cluster Zr17 and Zr-oxo chain Zr18 exhibit high PFOA adsorption capacities of 1051 and 1059 mg g?1, respectively, being at the forefront of Zr-oxo cluster-based adsorbents reported to date. Importantly, their PFOA adsorption capacities do not display any obvious effect in the presence of common interfering species or after five consecutive adsorption–desorption processes, laying a solid practical foundation for their application in PFOA-contaminated water systems. Furthermore, the endothermic PFOA adsorption processes are governed predominantly by monolayer chemisorption, demonstrating the existence of plentiful adsorption sites in Zr17 and Zr18. Their excellent PFOA adsorption performances probably originate from the synergistic effect of coordination bonds and hydrogen bonds formed between PFOA molecules and Zr-oxo clusters within these two materials. This work expands the promising application of Zr-oxo cluster-based coordination compounds in environmental protection. This journal is ? The Royal Society of Chemistry, 2026.
