MOF (Metal Organic Framework) microspheres and synthesis method thereof

The invention discloses MOF microspheres and a synthesis method thereof, and relates to the technical field of materials. The preparation method comprises the following steps: S1, dissolving inorganic salt with metal ions and an amino acid regulator in a solvent, and carrying out ultrasonic treatment to obtain a uniform and transparent mixed solution; s2, dissolving an organic bridging ligand in a solvent, and ultrasonically dissolving to obtain a uniform and transparent solution; and S3, pouring the solution obtained in the step S2 into the step S1, mixing, and synthesizing the MOF microspheres by a hydrothermal method. The MOF microspheres prepared by the invention are formed by self-assembling and stacking octahedral MOF units, and an octahedral structure of 30-80 nm is converted into the MOF microspheres of 0.5-3 [mu] m. The microsphere material has micropore, mesopore and macropore structures at the same time. The method for preparing the MOF microspheres is simple, the process is safe and controllable,
