摘要

本文以 2.5-双（三氟甲基）对苯二甲酸（H2BDC-(CF3)2）配体和三核锆烯构建单元为基础，构建了一种新型 CF3 功能化锆基金属有机四面体（ZrT-(CF3)2）。值得注意的是，在传统的溶热条件下获得了 ZrT-(CF3)2单晶，而微波辅助溶热法则进一步提高了产率和纯度。随后，系统评估了 ZrT-(CF3)2 对水杨酸（SA）新污染物的吸附性能，结果表明在最佳条件下，ZrT-(CF3)2 的最大吸附容量为 99.91 mg/g。此外，还根据实验结果和 DFT 模拟提出了一种可能的吸附机理。

Trifluoromethyl-functionalized zirconium-based metal-organic cage (ZrT-(CF3)2): An efficient adsorbent for salicylic acid removal

Herein, a novel CF₃-functionalized zirconium-based metal-organic tetrahedron (ZrT-(CF₃)₂) was constructed based on 2.5-bis(trifluoromethyl)terephthalic acid (H₂BDC-(CF₃)₂) ligand and trinuclear zirconocene building unit. Notably, the single crystals of ZrT-(CF₃)₂ was obtained under traditional solvothermal condition, while the yield and purity could be further improved by the microwave-assisted solvothermal method. Subsequently, the adsorption performance of ZrT-(CF₃)₂ for salicylic acid (SA) emerging contaminant was systematically evaluated, indicating a maximum adsorption capacity of 99.91 mg/g under optimal conditions. Furthermore, a possible adsorption mechanism was proposed based on experimental results and DFT simulations.
