Application

Tetraisopropyl Orthotitanate (Titanium Isopropoxide), the alkoxide of Ti(IV), is a widely used precursor of titanium oxide (TiO2) to form thin films, powders, nanomaterials and coatings. It is also employed as a starting material to prepare porous titanosilicates and ion-exchange materials. Tetraisopropyl Orthotitanate is also a material of interest for electronic coating applications.
Novel metal oxide/phosphonate hybrids were formed from titanium(IV) isopropoxide in a two-step sol-gel process. Starting material for barium-strontium-titanate thin films. Used to make porous titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes. Applied in the formation of a heterosupermolecule consisting of a TiO2 nanocrystallite-viologen electron acceptor complex whose light-induced electron transfer has been demonstrated.
