Nano titania is utilized across various sectors due to its multifunctionality:
Photocatalysis: One of the most notable applications is in photocatalysis, where nano titania is used to degrade organic pollutants, reduce air pollution, and purify water. Its ability to generate reactive oxygen species under UV light is leveraged for environmental cleanup. Cosmetics: In the cosmetics industry, nano titania is a popular ingredient in sunscreens due to its ability to absorb and scatter UV radiation, providing effective ultraviolet protection without leaving a white residue on the skin. Energy: It plays a role in enhancing the efficiency of solar cells, particularly in dye-sensitized solar cells, where it serves as a photoactive material. Biomedical Applications: In the medical field, nano titania is explored for drug delivery systems and as antibacterial agents due to its biocompatibility and ability to disrupt bacterial cell membranes.
