摘要: UiO-66是一种具有优异物理化学稳定性的金属有机骨架(MOFs)材料,近年来引起了研究者们的强烈关注。本文详细介绍了UiO-66的结构,重点探讨了溶剂热法过程中的一系列影响因素,包括使用不同的金属前体,改变合成温度、溶剂、各组分配比以及模板剂等,制备各种性能的UiO-66。针对溶剂热法合成效率较低的问题,介绍了微波合成法、微流控、连续流和无溶剂法等其它UiO-66的制备方法。为了扩大UiO-66的应用范围,对其有机配体进行功能化改性或与其他材料复合改性,具体介绍了改性后UiO-66在气体吸附、水处理、催化、电化学和化学传感等方面的应用。最后综述了利用UiO-66具有多孔特性构建分离膜方面的研究进展,具体阐述了纯UiO-66膜和UiO-66复合膜在气体分离和水处理方面的应用。

Abstract: As one of the metal organic frameworks (MOFs) with excellent physical and chemical stability, UiO-66 (UiO for University of Olso) has attracted considerable attention in recent years. In this review, the structure of UiO-66 was introduced and the solvothermal synthesis of UiO-66 was summarized in detail. The solvothermal synthesis could be affected by many factors, including the metal precursors, reaction temperature, solventsmolar ratio of the reagents and the template agents. In order to solve the intrinsic problems of solvothermal synthesis such as low efficiency and the need of a large amount of organic solvents, some new preparation methods including microwave synthesis, microfluidic, continuous flow and solvent-free methods were introduced. In order to extend the applications of UiO-66, some modification techniques, such as functionalization of organic ligands and coupling UiO-66 with other functional materials, were employed. The resulting functionalized UiO-66 was used in various applications including gas adsorption (CO2 separation and H2 recovery), water treatment (heavy metals and organics removal), catalysis, electrochemistry and chemical sensing. Finally, based on the porous property of UiO-66, pure UiO-66 membranes and UiO-66-based composite membranes especially the mixed matrix membranes were fabricated and their applications in gas separation and water treatment were reviewed.

Key words: metal organic frameworks (MOFs), synthesis, functionalization, separation, membranes
