Abstract

Mesoporous crystalline titania with large surface area was obtained with polymer templating. The wet gels, prepared by hydrolysis of Ti-alkoxide in ethanol, were immersed in a solution of triblock-copolymer, poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) [Pluronic, M.W. 12600], dried, and annealed. After annealing at 500°C, diffraction peaks of anatase were found. Pore size, pore volume and BET surface area of the annealed gels depended on the concentration of pluronic. The micelle-like aggregates of pluronic, which consisted of hydrophobic and hydrophilic blocks, were incorporated in the wet gel, and the shrinkage of gels during drying was restricted. Thus, the pore size and the surface area of annealed gels increased.
