摘要:

二维金属有机框架(MOFs)作为一类新型的二维多孔材料,具有厚度小、比表面积大、孔隙率高、可接触活性位点丰富等优点,在众多领域都具有研究和潜在的应用价值。本文简要综述了近年来二维MOFs的制备方法,包括“自上而下”和“自下而上”两种策略。自上而下法操作简单,有广泛的适用性;自下而上法可以通过控制实验条件在一定程度上实现对材料的可控制备。阐述了二维MOFs在电化学储能、催化、传感、气体分离等领域的应用研究。深层剖析了二维MOFs的特性对储能器件电化学性能以及反应催化活性的影响。此外,二维MOFs的高电导率和电荷转移率还促进了其在电化学传感器方面的发展;基于二维MOFs的分子筛膜也越来越受到研究人员的关注。最后指出了二维MOFs存在易团聚、厚度难以精确控制、制取成本较高、产率偏低等问题,提出了解决方案及其未来的发展方向。

Abstract:

As a new type of two-dimensional porous materials, two-dimensional metal-organic frameworks (2D-MOFs) have the advantages of small thickness, large specific surface area, high porosity and rich access to active sites. These advantages enable potential value of 2D-MOFs in energy storage, catalysis, sensing, separation and other fields. In this article, the preparation methods of 2D-MOFs in recent years were reviewed briefly, including top-down and bottom-up strategies. The top-down method was easy to operate and has wide applicability, while the bottom-up method can control the preparation of materials to a certain extent by controlling the experimental conditions. The influence of structural characteristics of 2D-MOFs on the electrochemical performance of energy storage devices and the catalytic activity of the reaction was analyzed elaborately. In addition, the high electrical conductivity and charge transfer rate of 2D-MOFs had promoted their development in electrochemical sensors. Molecular sieve membranes based on 2D-MOFs had also received increasing attention from researchers. Finally, the difficulty of controlling the thickness of 2D-MOFs, high cost and low yield were listed as current problems. It proposed that optimizing preparation scheme and doping and compounding it with other materials would be the future development directions to improve the performance of 2D-MOFs.

Key words: two-dimensional metal-organic frameworks (2D-MOFs), preparation, electrochemical energy storage, catalysis, sensor, separation
