MOFs (Metal-Organic Frameworks) material controllably synthesized by micro-emulsion method and preparation method of MOFs material

The invention provides an MOFs material controllably synthesized by a microemulsion method and a preparation method of the MOFs material. The preparation method comprises the following steps of: preparing three quaternary ammonium salt ionic liquids, namely [C2DMEA] [Im], [C4DMEA] [Im] and [C6DMEA] [Im]; adding [C2DMEA] [Im], DMSO, ethyl acetate, [C4DMEA] [Im], DMSO, ethyl acetate and [C6DMEA] [Im], DMSO and ethyl acetate into three bottles respectively, and stirring well to obtain three micro-emulsion systems; and respectively adding an organic ligand and a metal salt into the obtained three micro-emulsion systems, stirring until precipitates are separated out, centrifugally separating out the precipitates, and washing the precipitates to obtain three MOFs materials with different morphologies. According to the method, the aim of accurately regulating and controlling the structure and the morphology of the MOFs material is fulfilled by regulating the length of an alkyl chain of the ionic liquid and the conce
