What Materials are Commonly Used as Photocatalysts?
A variety of materials can serve as photocatalysts, but some of the most commonly used include titanium dioxide (TiO₂), zinc oxide (ZnO), and cadmium sulfide (CdS). Titanium dioxide is particularly popular due to its stability, non-toxicity, and high efficiency under UV light. Researchers are also exploring carbon-based materials like graphene and carbon nanotubes for photocatalytic applications.
