TiO2 is highly valued in catalysis for several reasons:
1. Photocatalysis: TiO2 can absorb ultraviolet light and generate electron-hole pairs, which can subsequently drive chemical reactions. This property is utilized in applications such as water splitting to produce hydrogen, and air and water purification.
2. Surface Properties: The large surface area and high surface energy of TiO2 nanoparticles enhance their interaction with reactants, promoting higher catalytic efficiency.
3. Chemical Stability: TiO2 is resistant to corrosion and chemical degradation, which makes it suitable for long-term catalytic processes.
