TiOEt4

Titanium ethoxide, also known as tetraethoxy titanium or titanium(IV) ethoxide, has the chemical formula Ti(OC2H5)4. It is an organometallic compound that appears as a colorless liquid at room temperature. It is soluble in ethanol and other organic solvents. Titanium ethoxide is sensitive to moisture and will hydrolyze in the presence of water, forming titanium dioxide and ethanol. This hydrolysis reaction is often exploited in sol-gel processes for the preparation of titanium dioxide thin films and powders.

The compound is synthesized through the reaction of titanium tetrachloride with ethanol. It finds applications in various fields, including catalysis, materials science, and as a precursor for the deposition of titanium dioxide coatings. These coatings can be used for purposes such as photocatalysis, anti-reflective layers, and as dielectric materials. The reactivity of the ethoxy groups allows for controlled hydrolysis and condensation reactions, making it a versatile building block for creating advanced ceramic materials. Due to its moisture sensitivity, titanium ethoxide must be handled and stored under anhydrous conditions to prevent degradation.
