Update on Interfacial Charge Transfer (IFTC) Processes on Films Inactivating Viruses/Bacteria under Visible Light: Mechanistic Considerations and Critical Issues

This review presents an update describing binary and ternary semiconductors involving interfacial charge transfer (IFCT) in composites made up by TiO<sub>2</sub>, CuO, Ag<sub>2</sub>O and Fe<sub>2</sub>O<sub>3</sub> used in microbial disinfection (bact...
