The present invention belongs to the field of photocatalytic composite materials, and specifically relates to a K-C3N4@Bi2WO6 multi-level heterogeneous material, a rapid synthesis method thereof, and its application in photocatalytic sterilization and degradation of organic pollutants. The K-C3N4@Bi2WO6 multi-level heterogeneous material provided by the present invention uses a two-dimensional porous layer structure K-C3N4 as a carrier to load zero-dimensional Bi2WO6 quantum dots. The heterogeneous material is controllably constructed by using ion exchange technology, and the K-C3N4 and Bi2WO6 are reacted in an in-situ calcination process. 6‑ x Br x Ion exchange spontaneously occurs in aqueous solution to generate KBr. At the same time, the unsaturated C atoms around the N defects on K-C3N4 and the dangling oxygen bonds on the surface of Bi2WO6 make the interface between the two close and increase the contact area, and provide a transmission channel for photogenerated electrons, greatly promoting the separation of photogenerated electron-hole pairs. This method has the advantages of being simple, fast, and effective in constructing heterogeneous materials. The obtained K-C3N4@Bi2WO6 multi-level heterogeneous material has excellent rapid low-temperature degradation and sterilization properties of organic pollutants.

This invention discloses a method for preparing a self-healing hydrogel with both sensing and antibacterial properties. The invention uses a hydrogel prepared from acrylamide (AM) and 2-(methacryloyloxy)ethyl dimethyl-(3-sulfopropyl)ammonium hydroxide (SBMA) and cellulose nanofibers (CNF) as a matrix, silver-coated polydopamine nanoparticles (Ag@PDA NPs) as antibacterial and conductive agents, and 2-hydroxy-4'-(2-hydroxyethoxy)-2-methylphenylacetone (I2959) and polyethylene glycol diacrylate (PEGDA) as photoinitiators and crosslinking agents. A multifunctional hydrogel with multiple dynamic reversible bonds is prepared by ultraviolet light-initiated self-polymerization. By constructing various dynamic reversible interactions, including covalent and non-covalent bonds and interionic interactions, a self-healing Ag@PDA NPs / AM / SBMA / CNF hydrogel was obtained. Ag and DA were introduced to prepare Ag@PDA with antibacterial, adhesive, and electronic conductivity properties, while zwitterionic SBMA was introduced to provide ionic conductivity. The synergistic effect of these two compounds endows the hydrogel with electrical conductivity. The hydrogel dressing prepared by this method can achieve rapid sterilization while possessing excellent biocompatibility, high adhesion, high conductivity sensing ability, and environmental adaptability.
