Monolithic nanocrystalline anatase titania aerogels are synthesized by the epoxide sol-gel method followed by thermal annealing at 550 C. These aerogels are formed by {approx}10-20 nm size anatase nanoparticles which are randomly oriented and interconnected into an open-cell solid network. Aerogel monoliths have an apparent density of {approx}6% and a surface area of {approx} 100 m{sup 2} g{sup -1}. High-resolution transmission electron microscopy and soft x-ray absorption near-edge structure spectroscopy reveal good crystallinity of the anatase nanoparticles forming the aerogel skeleton.
