General description

Titanium(IV) butoxide, also known as titanium tetra butoxide or tetrabutyl titanate. It appears as a colorless to light yellow viscous liquid and is typically sensitive to moisture and air. It is widely used as a precursor in the production of titanium dioxide (TiO2) thin films through sol-gel processes. It plays a key role in the development of ceramic coatings and nanostructured materials. Titanium(IV) butoxide is also commonly employed as a catalyst or catalyst component in esterification and transesterification reactions.

Application

Used to prepare nanosized titania in the anatase form and ferroelectric Bi4Ti3O12 thin films. Used in the preparation of nanocrystalline TiO2 powders at room temperature.
Titanium(IV) butoxide can be used as:
  • A precursor to prepare the titanium dioxide (TiO2) nanoparticles or thin films via sol-gel method. These TiO2 nanoparticles are suitable for ultraviolet photodetector applications on flame retardant-4 (FR-4) boards.
  • A precursor to synthesize TiO₂ nanoparticles via polyol-mediated method.
  • A precursor for synthesizing anatase-phase TiO₂ nanoparticles through a microwave-assisted method. The resulting nanoparticles are carbon-coated and employed as an anode material in sodium-ion batteries.
  • A precursor material for the preparation of titanium oxide (TiO2) for various applications such as dye sensitized solar cells (DSSCs), photo-catalytic and self-cleaning based coatings

Features and Benefits

Titanium(IV) butoxide exhibits:
  • High Purity (≥97.0%): Ensures minimal contamination in the final product, which is crucial for applications in energy storage, catalysis, and optics.
  • Liquid at Room Temperature: Easy to handle and mix with solvents or other reagents.
  • High solubility: Soluble in organic solvents such as alcohol and ether but insoluble in water. Compatible with Various Synthesis Methods
  • Reproducibility: High purity and consistent reactivity ensure reproducible results across batches and experiments.
