How is TiO₂ Modified to Enhance its Catalytic Properties?
Researchers are exploring various methods to enhance the catalytic properties of TiO₂: 1. Doping: Adding elements like nitrogen, sulfur, or transition metals can shift the bandgap of TiO₂, making it active under visible light. 2. Composite Materials: Combining TiO₂ with other materials, such as graphene or carbon nanotubes, can enhance its photocatalytic efficiency. 3. Nanostructuring: Creating TiO₂ nanostructures increases the surface area and improves light absorption, thereby boosting its catalytic performance.
