Abstract
The present invention discloses a method for preparing an ultra-thin Ni—Fe-MOF nanosheet, which comprises the steps of dissolving an organic ligand in an organic solvent, dripping the resulting solution to an aqueous solution containing a nickel salt and an iron salt, mixing uniformly and reacting at 140-160° C. for 3-6 h to obtain the ultra-thin Ni—Fe-MOF nanosheet, wherein the organic ligand is terephthalic acid and/or disodium terephthalate, and the organic solvent is N,N-dimethylacetamide and/or N,N-dimethylformamide. The present invention discloses an ultra-thin Ni—Fe-MOF nanosheet, and use thereof. The preparation method does not require a surfactant, the surface of the product is neat and easy to be cleaned, and the large-scale synthesis of 2D ultra-thin MOF materials can be realized.
