These properties make TiO2 an ideal material for photocatalytic applications, particularly in environmental and industrial contexts.
How Does Titanium Dioxide Photocatalysis Work?
When titanium dioxide is exposed to UV light, it generates electron-hole pairs on its surface. These electron-hole pairs are highly reactive and can break down organic contaminants in the air or water, making TiO2 a key material for environmental applications. As a result, TiO2 photocatalysts are utilized in air purifiers, water treatment systems, and coatings for self-cleaning surfaces. Its unique properties are being explored for renewable energy applications, especially in hydrogen production via water splitting and as a component in solar cells.
