Abstract

The presence of sulfate ions markedly affects the nanopore structure of titania-sulfate aerogels. In TiO₂-SO₄^2- materials, unlike in zirconia-sulfate aerogels, the larger sulfate load stimulates formation of a more consolidated structure. The XRD analysis shows that even a crystalline phase (anatase) may be present in fresh, dry aerogels, which, perhaps, is the first observation of this phase in sol-gel titania obtained from the low temperature drying process.
