Synthesis of Microcrystalline Titania in Organic Media

Abstract

Reaction of oxobis(2, 4-pentanedionato-O, O')titanium (TiO(acac)₂) or titanium isopropoxide (TIP) in various organic media was examined and found to afford microcrysta lline anatase. The product having the smallest crystallite size and the largest sur face area was obtained by the reaction of TiO(acac)₂ in toluene at 250 °C. The product preserved relative ly high surface area even after calcination at 550 °C in an air flow.
