Rutile TiO2 can be used in photocatalytic water splitting for hydrogen production, a promising method for generating clean energy from solar power.

2. Pigments and Coatings:
White Pigments:
Rutile TiO2 is commonly used as a white pigment in paints, coatings, and plastics due to its high refractive index and excellent opacity. It provides brightness, durability, and UV protection in various products.
Protective Coatings:
The high thermal stability and UV absorption properties of rutile TiO2 make it ideal for protective coatings. It is commonly used in automotive, architectural, and industrial coatings where long-lasting protection against environmental factors is necessary.
Self-Cleaning Surfaces:
Due to its photocatalytic properties, rutile TiO2 is often used in self-cleaning coatings. When exposed to sunlight, it breaks down organic contaminants on surfaces, allowing them to be easily washed away by rain or water.

3. Electronics and Sensors:
Electronics and Semiconductor Devices:
Rutile TiO2 is used in a variety of electronic applications, including sensors and capacitors. Its semi-conductive properties make it suitable for use in devices that require stable performance under various environmental conditions.
Gas Sensors:
TiO2 nanoparticles, including the rutile form, are employed in gas sensors to detect the presence of gases such as ammonia, nitrogen dioxide, and other pollutants. The material’s electrical properties change in response to different gas concentrations, making it useful in environmental monitoring.

4. Cosmetics and Personal Care:
Sunscreens and UV Protection:
Rutile TiO2 is commonly used in sunscreens and cosmetic products for its ability to block harmful UV radiation. It provides broad-spectrum protection against both UVA and UVB rays, making it a critical ingredient in sun care products.
Cosmetic Pigments:
Rutile TiO2 is also used as a pigment in cosmetics, providing brightness and opacity in products like foundations, powders, and creams.

Safety and Handling

Health Considerations:
Titanium dioxide is considered safe in most applications, though precautions should be taken when handling TiO2 nanopowder. Inhalation or skin contact should be avoided, and protective measures such as gloves, masks, and goggles are recommended during handling.
Environmental Impact:
TiO2 rutile is generally regarded as non-toxic and environmentally safe. However, as with all nanoparticles, research is ongoing to understand its long-term environmental effects. Proper disposal methods and precautions should be followed to minimize environmental exposure.
