WebWhen the photocatalyst absorbs light, it reacts with the water and oxygen in the air to produce reactive oxygen species (O₂⁻ and ·OH). The strong oxidizing power of these reactive oxygen species breaks apart the chemical bonds within odors and other substances with which they come into contact. The odor components and other substances ...
