Application
The Titanium Dioxide Catalyst Nanopowder serves as a versatile catalyst primarily utilized in various industrial and environmental applications due to its unique photocatalytic properties and high refractive index. This nanopowder is valued for its ability to efficiently decompose organic pollutants in water and air, effectively contributing to environmental detoxification and remediation processes. In automotive applications and power stations, it aids in reducing harmful exhaust emissions by catalyzing the breakdown of nitrogen oxides and volatile organic compounds. Furthermore, in the realm of renewable energy, it is employed in dye-sensitized solar cells to enhance electricity production. Its photoreactivity under UV light also makes it suitable for creating antimicrobial coatings, anti-fogging solutions, and self-cleaning surfaces. With its intrinsic ability to scatter both visible and ultraviolet light, this nanopowder finds application in the formulation of sunscreens, cosmetics, and coatings, enhancing their performance by providing brightness, UV protection, and increased durability.
