Research progress of photocatalytic materials for removing viruses in water

With its advantages such as good stability, high efficiency and low cost, photocatalytic technology has been gradually applied in the field of water disinfection, where a series of reactive oxygen species generated by photocatalysts can effectively inactivate the pathogenic microorganisms in water. Because the structure and resistance of viruses are quite different from those of other microorganisms, this article only focuses on the research progress of photocatalytic materials for removing viruses in water. The oxidation and disinfection principles of photocatalytic technology are introduced, the advantages and disadvantages of traditional disinfection technology for viruses removal are discussed, and the applications of TiO₂-based photocatalysts and TiO₂-free photocatalytic materials are summarized. Finally, we conclude that the future photocatalytic materials should be developed in the directions of reducing preparation costs, improving photocatalytic efficiency, and enabling practical large-scale engineering applications.
