However, recent findings show that VOC disruption is associated with the release of toxins in the air, which questions the prudence of TiO2-doped paints for air purification purposes.155 If effective, the use of TiO2 photocatalysis for SARS-CoV-2 inactivation would be particularly useful for surface decontamination using TiO2-doped paints, aerosol decontamination using air filtration filters and ventilation systems impregnated with TiO2 that can be exposed to UV light, and for wastewater treatment.
