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 beca.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).
