photocatalytic oxidation


Photocatalytic oxidation (PCO) is a process that uses a catalyst, typically titanium dioxide, and ultraviolet light to break down pollutants into water, carbon dioxide and detritus. 1 The UV light provides the energy that allows the catalyst to work, converting water in the air into a form that turns molecules of pollution into more harmless substances. 2 This process has the advantage of completely transforming the harmful chemicals and effectively destroying them, rather than simply trapping pollutants. 2 However, it also produces tiny amounts of ozone, a toxic air pollutant. 2
