TiO2 Based Photo-Catalysis for Virus Disinfection

Abstract

This review considers the current literature that is focused on the interface nanostructure/cell-wall microorganism to understand the annihilation mechanism. In this report, photocatalysis is discussed for viral disinfection including TiO 2 photocatalysis and other metal-containing photocatalysis. TiO 2 based materials and its composites, metal-TiO 2 systems, TiO 2 heterojunction systems with other semi-conductors, and TiO 2 systems with graphene and other carbonaceous materials are discussed in detail. Some practical uses of titanium dioxide for photocatalytic disinfection processes for the effective prevention/eradication of microorganisms, considering the resistance that the microorganism could develop without the appropriate regulatory aspects for human and ecosystem safety are also discussed.
