  • Publication number: 20240209158
    Abstract: The invention provides an ultra-small nano metal organic framework material and a preparation method thereof. The MOFs material is prepared from a low-cost metal source and organic ligands through solvothermal reaction, wherein metal ions in the metal source are at least two of ferric ions, bivalent copper ions or bivalent zinc ions; the ligands are at least two of terephthalic acid, 2-aminoterephthalic acid, meso-tetra (4-carboxyphenyl) porphin, 2-nitroterephthalic acid, 2-hydroxyterephthalic acid and trimesic acid; the solvent is formed by mixing ethanol and o-dichlorobenzene according to the volume ratio of (1-3):1. The particle size of the prepared MOFs material is 2-10 nm, and the prepared MOFs material is high in dispersity, specific surface area and activity. The MOFs material aqueous solution can generate a large amount of active oxygen in an ultrasonic environment, and has extremely high medical value.
