TLDR
In this article, it was shown that the virus-inactivation properties of TiO2 are mainly based on the direct contact between nanoparticles and virus particles, and the inactivation effect was observed when the incubation was performed in darkness.Abstract:
Titanium dioxide (TiO2) in a suspension or absorbed on a film possesses bactericidal and virucidal properties caused by photocatalytic reactions. Our electron microscopic examinations showed that titanium dioxide nanoparticles destroyed the influenza virus after 30 min incubation. Virological studies revealed the inactivation of the influenza virus by TiO2, depending on the concentration of nanoparticles and the incubation period. The inactivation effect was observed when the incubation was performed in darkness, unlike the TiO2 suspension. We propose that the virus-inactivation properties of TiO2 are mainly based on the direct contact between nanoparticles and virus particles.read more

Different Inactivation Behaviors of MS-2 Phage and Escherichia coli in TiO2 Photocatalytic Disinfection
TL;DR: It seems that MS-2 phage is inactivated mainly by the free hydroxyl radical in the solution bulk but that E. coli might also be inactivated by other ROS, such as O2·− and H2O2, according to the present results.
