Titanium DiOxide Nanoparticles
Introduction:
Titanium dioxide (TiO₂) nanoparticles are nanoscale particles of titanium dioxide, a naturally occurring oxide of titanium. TiO₂ is a white, odorless powder commonly used in various industries, but when reduced to the nanoscale, it exhibits unique properties that differ from its bulk counterpart. These nanoparticles have high surface area, strong photocatalytic activity, and exceptional UV-light absorption capabilities, which make them valuable in a range of applications, particularly in environmental, energy, and biomedical fields.
Titanium dioxide exists in different crystalline forms, with the most common being anatase, rutile, and brookite. Among these, anatase and rutile are the most frequently used in nanoparticle applications, with anatase known for its superior photocatalytic properties.
Properties
High Surface Area: TiO₂ nanoparticles have a large surface-to-volume ratio, which enhances their reactivity and makes them suitable for catalytic applications.
Photocatalytic Activity: Titanium dioxide is well-known for its ability to catalyze chemical reactions under UV light. This photocatalytic property is useful in environmental remediation, energy production, and other processes that require light-induced chemical reactions.
UV Light Absorption: TiO₂ nanoparticles can absorb UV radiation, which makes them ideal for use in sunscreen products and other applications where UV protection is needed.
Chemical Stability: TiO₂ is chemically stable, non-toxic, and biocompatible, which makes it suitable for use in various fields, including cosmetics and medical applications.
Optical Properties: TiO₂ nanoparticles exhibit unique optical properties, such as high refractive index, which make them useful in coatings, pigments, and in the production of optical devices.
Non-toxic and Biocompatible: Titanium dioxide is non-toxic in most applications, and when used in nanoparticle form, it remains safe for many consumer and medical applications.
