Application

Titanium ethoxide is used widely as a precursor for the synthesis of Ti4+ ions titania nanoparticles by various techniques such as :
  • in the sol-gel synthesis of free-standing ferroelectric lead zirconate titanate nanoparticles
  • spherical titania cores, produced either by hydrolysis of Ti(IV) ethoxide droplets in contact with water vapor or
  • by preadsorption of the titanium alkoxides into/onto the clay mineral platelets and their subsequent hydrolysis and calcination.

Mesoporous Oxides and Their Applications to Hydrogen Storage

Mesoporous materials, such as aerogels, offer advantages for practical hydrogen storage. They have large surface areas, open porosity, small pore sizes, and the ability to coat the surface with one or more compounds.
