Photocatalytic materials are substances that accelerate a chemical reaction upon exposure to light, typically ultraviolet (UV) or visible light. These materials possess a unique ability to harness solar energy, converting it into chemical energy, which drives various reactions. Titanium dioxide (TiO2) is one of the most well-known photocatalysts, but other materials like zinc oxide (ZnO), cadmium sulfide (CdS), and certain metal oxides are also widely used.
