摘要：
For the first time, amorphous TiO2 aerogels with a high specific surface area (420 m(2)/g) and low geometric density ('-0.1 g/cm(3)) were obtained using epoxide-induced gelation in N, N-dimethylformamide. Impregnation of the resulting aerogels with aqueous solutions of H(2)PtCl(6 )and NaBH4 followed by thermal annealing made it possible to obtain Pt/TiO2 photocatalysts, which showed very high activity for titanium dioxide-based aerogels in the generation of hydrogen from aqueous alcohol solutions (~5 mmol(H2) h( -1) g(-1)).
