Preparation and Application of Ultra-Thin Two Dimensional MOF Nanomaterials

Ultra-thin two dimensional metal-organic framework (MOF) nanomaterial is a kind of MOF materials. Different from the traditional bulk MOF materials, the ultra-thin sheet structure endows it with unique properties such as high specific surface area, rich coordination unsaturated metal sites and so on, which can effectively improve the performance of MOF in catalysis, separation and sensors. In this paper, the research progress on the construction and preparation methods of ultra-thin two dimensional MOF nanomaterials in recent years is reviewed, including top-down method, bottom-up method and 2D oxide sacrifice approach. At the same time, this paper discusses the application prospects of ultra-thin two dimensional MOF nanomaterials in the fields of gas adsorption and gas separation, catalysis, energy storage, sensing platform, and further analyzes the challenges and opportunities faced by the research of ultra-thin two dimensional MOF nanomaterials in the future.
