COVID-19 and Photocatalytic Oxidation Indoor Air Purification
What is Photocatalytic Oxidation?
The photocatalytic oxidation (PCO) process involves combining ultraviolet light irradiation with a titanium dioxide coated filter. Here’s how the titanium dioxide catalyst in an air purifier breaks apart molecules of air pollution:
- When UV light shines on the titanium dioxide, electrons are released at its surface.
