What are the Key Mechanisms Involved in Photocatalysis?
Photocatalysis involves several key mechanisms: 1. Light Absorption: The photocatalyst absorbs photons, generating electron-hole pairs. 2. Charge Separation: Electrons and holes migrate to the surface of the photocatalyst. 3. Chemical Reactions: The electrons and holes participate in redox reactions, breaking down pollutants or producing hydrogen.
