| 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. |
