Method for preparing micro-nano metal organic framework by oil-water two-phase method and application of micro-nano metal organic framework

The invention belongs to the technical field of nano materials, and relates to a method for preparing a micro-nano metal organic framework by an oil-water two-phase method and application of the micro-nano metal organic framework. The preparation method comprises the following steps: mixing a fatty acid precursor, a metal salt and a solvent to prepare a precursor solution, dissolving a ligand in an organic solvent, mixing with the precursor solution, heating and stirring, collecting a solid product, and washing to obtain the micro-nano metal organic framework which has the characteristics of high crystallization, uniform size and regular morphology. The coordination reaction of the metal oleate (solid) and the ligand is mainly carried out on the interface of an oil-water solution, and different from the traditional solvothermal method, the preparation method disclosed by the invention is simple and convenient in steps, and the designed oil-water two-phase interface can well control the nucleation and growth p
