摘要：
This paper presents an approach to improving the selectivity of gas sensors based on nanocrystalline tin dioxide. We demonstrate that chemical modification of the surface of SnO2 crystallites with catalytic metal oxide and gold clusters considerably enhances the selectivity of their sensing response to a variety of reducing gases at gas concentrations near the maximum permissible level. This approach can be used to produce “electronic nose” multisensor arrays.
