As one of porous metal–organic frameworks, zeolitic imidazolate frameworks (ZIFs) are typical crystalline materials with tetrahedral clusters such as ZnN4 and CoN4 linked by imidazolate ligands. Due to facile synthesis, regulated nanostructures and tunable pore sizes, various ZIFs have been extensively utilized in energy storage, separation, and heterogeneous catalysis, whereas few reviews concerning the recent advances in the removal of environmental pollutants on ZIFs have been examined systemically to date. Herein, we first review the synthesis and properties of ZIFs, and then emphasize in detail the removal of various environmental pollutants such as noxious gases, organic pollutants, heavy metals and radionuclides on ZIFs in recent five years. The interaction mechanism (e.g., adsorption, redox and co-precipitation) of ZIFs and various contaminants is proposed using spectroscopic, modeling and theoretical calculations. Finally, the prevailing challenges and further prospects in environmental pollution remediation are proposed to guide the development and actual application of ZIFs. Hopefully, this review is dedicated to material scientists and environmental chemists for broadening the actual application of ZIFs in environmental remediation.

沸石咪唑酯骨架(ZIFs)在环境修复中应用的最新进展:综述

作为多孔金属有机骨架之一,沸石咪唑骨架(ZIFs)是典型的结晶材料,具有四面体簇,例如通过咪唑配体连接的ZnN 4和CoN 4 。由于易于合成、可调节的纳米结构和可调节的孔径,各种 ZIF 已被广泛用于能量存储、分离和多相催化,而迄今为止,关于 ZIF 去除环境污染物方面的最新进展的综述很少。在此,我们首先回顾了 ZIFs 的合成和性质,然后详细强调了近 5 年来 ZIFs 对有害气体、有机污染物、重金属和放射性核素等各种环境污染物的去除。交互机制(使用光谱、建模和理论计算提出了 ZIF 和各种污染物的吸附、氧化还原和共沉淀)最后,提出了环境污染修复的普遍挑战和进一步的前景,以指导 ZIF 的开发和实际应用。希望这篇评论致力于材料科学家和环境化学家,以扩大 ZIF 在环境修复中的实际应用。
