Title:
PHOTOCATALYTIC ANTIBACTERIAL MATERIAL, PREPARATION METHOD THEREFOR, AND PHOTOCATALYTIC ANTIBACTERIAL AGENT
Document Type and Number:
WIPO Patent Application WO/2023/035451
Kind Code:
A1
Abstract:
A photocatalytic antibacterial material, a preparation method therefor, and a photocatalytic antibacterial agent. The photocatalytic antibacterial material comprises a visible light catalyst matrix and a conductive auxiliary agent; the conductive auxiliary agent is used for separating electrons and holes after the visible light catalyst matrix corresponds to visible light, and the conductive auxiliary agent is loaded on the visible light catalyst matrix. By means of the synergistic effect achieved between the conductive auxiliary agent and the visible light catalyst matrix, the photocatalytic antibacterial material is endowed with efficient, stable and long-acting antibacterial disinfection effects. The photocatalytic antibacterial material prepared by using the photocatalytic antibacterial material preparation method has stable properties such as antibacterial and antiviral effects, and high efficiency and economic cost reduction are achieved. The photocatalytic antibacterial agent comprises the photocatalytic antibacterial material.
