| description | The invention discloses polyphenol hydroxyl COFs (covalent organic frameworks) aerogel rich in hydrogen bond donors as well as a preparation method and application of the polyphenol hydroxyl COFs aerogel. The preparation method comprises the following steps: dispersing an aromatic polyammonia monomer and a phenolic hydroxyl group-containing aromatic polyaldehyde monomer into a benign solvent to form a uniform suspension, then adding an acid solution for catalysis, carrying out a Schiff-base reaction to obtain wet gel, and carrying out aging and supercritical drying on the wet gel to obtain the phenolic hydroxyl group-containing aromatic polyaldehyde hydrogel. The obtained COFs aerogel material which is stable in molecular structure, has a special pore structure and good mechanical properties and is rich in phenolic hydroxyl group modifications is applied to adsorption separation of antibiotics and/or harmful heavy metal ions in an aqueous solution as an adsorbent, has the advantages of large adsorption capaci |
