[0014] The iron oxide (Fe3O4) surface of this invention contains a large amount of tannic acid. These tannic acids, with their abundant functional groups, provide sufficient active sites for the subsequent chelation reaction of zinc oxide on this surface. As a connector between the two, the tannic acid enables zinc oxide and iron oxide to form a stable shell structure. When zinc oxide receives light energy, photoelectrons are transferred to the surface of the internal iron oxide nanoparticles via the tannic acid. Valence band electrons are excited more easily to reach an excited state. Furthermore, due to the connection between zinc oxide and iron oxide by the tannic acid, the photogenerated electrons and holes generated by light are prevented from coupling. The retention of a large number of photogenerated electrons and holes, as an antibacterial material, can more readily convert hydroxyl radicals, greatly increasing the antibacterial performance. Combined with imidazole salts, molecular docking is achieved through hydrogen bonding to construct supramolecular assemblies, which penetrate deep into bacteria for internalization, providing targeted antibacterial effects and significantly improving antibacterial capacity. Simultaneously, the addition of essential oils achieves antibacterial and odor-removing effects. Attached Figure Description
