Nanosized Сe-doped SnO2 nanocomposites as perspective materials for adsorption semiconductor sensors

Nanosized Ce-containing materials based on SnO 2 with Sb additives were obtained by a sol-gel method using tin (II) oxalate, hydrogen peroxide, antimony (III) chloride and cerium (III) acetate as precursors. The average particle sizes of the synthesized materials were found to be ca. 9 nm. It was sh...

Description
Summary:Nanosized Ce-containing materials based on SnO 2 with Sb additives were obtained by a sol-gel method using tin (II) oxalate, hydrogen peroxide, antimony (III) chloride and cerium (III) acetate as precursors. The average particle sizes of the synthesized materials were found to be ca. 9 nm. It was shown that the sensors based on these nanocomposites exhibit high sensitivities to hydrogen microconcentrations in air, long-term stabilities of their parameters and demonstrate a wide range of the detectable hydrogen concentration (44 − 935 ppm H 2 in air).
