SYNTHESIS OF MICROCRYSTALLINE TITANIA IN ORGANIC MEDIA

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 microcrystalline anatase. The product having the smallest crystallite size and the largest surface area was obtained by the reaction of TiO(acac)2 in toluene at 250-degrees-C. The product preserved relatively high surface area even after calcination at 550-degrees-C in an air flow.
