Pure TiO2 and mixed oxide samples of TiO2 and SnO2 sintered samples having different surface areas were synthesized using a heat treatment in H-2 bearing gas. Nanostructures of solid solutions and spinodally-decomposed samples of mixed oxides were compared to the oriented nanofibers formed in pure TiO2 created by the same heat treatment. Comparisons between the sensing characteristics of the samples were made to determine that the samples with higher surface areas were more sensitive to H-2 in the presence Of O-2.
