Monodisperse spherical TiO2 particles easily obtained

Highly spherical, monodisperse particles made of titanium oxide can be synthesised in a sub and micrometre range under very mild conditions in a facile synthesis using commercial reactants. Applications in catalysis and photonics

Necesidad del Mercado: Titania, thanks to its high refractive index and electronic properties, has attracted technological interest in fields such as catalysis, photonics etc. Typical synthesis techniques have failed to produce monodisperse TiO2 particles with ease in a broad range of sizes. Monodispersity is crucial in some such areas.

Solución propuesta: A simple metal alkoxide hydrolysis is demonstrated to be capable under several variations of our technology to produce monodisperse spherical particles of a wide range of sizes from a fraction to several micrometres. The reaction takes place at room temperature and mild conditions not requiring special set up.
