An enhancement of selectivity of sensor materials, based on nanocrystalline SnO 2 is reported. Selectivity toward target gases such as CO, NO 2 , NH 3 , H 2 S and acetone vapor, could be achieved by selection of catalytic cluster distributed over the surface of thick film material. Presented results allow us to propose application of obtained materials in “electronic nose” sensor systems.
