Defected NUS-8 nanosheet and preparation method thereof

The invention discloses a defective NUS-8 nanosheet and a preparation method, and belongs to the technical field of metal organic framework materials, a solvothermal method is adopted, a ligand is dissolved and reacts in a solvent, reaction conditions are simple and convenient, too complex steps are not involved, and repeatability is high; the preparation method has the advantages that the yield is high, more nanosheets can be prepared by increasing the using amount of the ligand, partial replacement of tricarboxylic acid by dicarboxylic acid is realized, and compared with pure NUS-8, the obtained defective NUS-8 nanosheet suspension (Zr-MTDm-BTBn suspension) has the advantages that the pore size of Zr-MTDm-BTBn only changes, and the change belongs to a nano level, so that the surface appearance is not greatly changed, and the preparation method is simple and convenient. The pore diameter is changed by partially replacing a tricarboxylic acid ligand with a dicarboxylic acid ligand to coordinate with a seconda
