Photocatalytic oil-water separation material and preparation method thereof

A photocatalytic oil-water separation material prepared by a preparation method, the preparation method comprising the following steps:

• step S1, sequentially cleaning a base material and a metal-doped material by using an alcohol solvent, a dilute acid solution and deionized water, and drying for later use;
• step S2, preparing a mixed solution of an amine monomer and an acid-alkali buffer reagent, soaking the base material in the mixed solution, and reacting under an oscillation condition, to obtain the base material attached with amine monomer polymer;
• step S3, dissolving a soluble metal additive and an organic ligand reagent comprising carboxylic acid or pyridine into an organic solvent, and uniformly performing ultrasonic stirring, to obtain a photocatalytic MOFs reaction solution;
• step S4, placing the metal-doped material in the step S1, the base material that has been reacted in the step S2 and the MOFs reaction solution obtained in the step S3 into a reaction kettle for performing hydrothermal reaction;
• and
• step S5, cleaning excess impurities on surfaces of the base material that has been reacted in the step S4 by using anhydrous methanol or anhydrous ethanol and then drying, to obtain the photocatalytic oil-water separation material;
• and wherein
• a metal element comprised in the soluble metal additive is different from that of the metal-doped material, and a main metal component comprised in the base material is different from the metal element of the metal-doped material.
