Extermination of influenza virus H1N1 by a new visible-light-induced photocatalyst under fluorescent light

A new visible-light-induced photocatalyst based on several transition metals (iron, magnesium and manganese) loaded TiO2 was evaluated for its anti-viral activity with influenza virus H1N1. Under a fluorescent lamp of 1000lx, lambda > 410 nm, the virus was eradicated to more than 99% within 30 min. Since this photocatalyst can be used for coating plastics, wall papers and walls, it would be desirable to use this photocatalyst to reduce viral transmission via droplets and aerosols as well as surface contact for disinfection.
