TiO2 nanoparticles, also known as titanium dioxide nanoparticles, are a type of engineered nanomaterial with unique properties that make them useful in various applications. They are composed of titanium dioxide (TiO2), a white, inorganic compound that occurs naturally in several polymorphic forms, including anatase, rutile, and brookite. Nanoparticles are particles with at least one dimension in the nanoscale range, typically between 1 and 100 nanometers.

TiO2 nanoparticles are widely used in industries such as cosmetics, sunscreens, and paints due to their excellent UV protection properties. They are also employed in photocatalysis, where they can degrade organic pollutants under UV light, making them useful in water treatment and air purification. Additionally, TiO2 nanoparticles have been explored for their potential in energy applications, such as in dye-sensitized solar cells and hydrogen production.

Despite their numerous benefits, the environmental and health impacts of TiO2 nanoparticles are a subject of ongoing research. Concerns have been raised about their potential toxicity, particularly when inhaled or ingested, as well as their environmental persistence and potential accumulation in ecosystems. As a result, there is a growing need for further studies to better understand the risks and benefits associated with TiO2 nanoparticles.
