Catalytic properties of oxide nanoparticles applied in gas sensors

Lutic, D ; Strand, M ; Lloyd-Spetz, A ; Buchholt, K ; Ieva, E ; Kall, PO and Sanati, Mehri LU (2007) In Topics in Catalysis 45(1-4). p.105-109
Abstract
A series of gas sensing layers based on indium oxide doped with gold were prepared by using the aerosol technology for deposition as the active contact layer in a metal oxide semiconductor capacitive device. The interaction between the measured species and the insulator surface was quantified as the voltage changes at a constant capacitance of the device. The sensor properties were investigated in the presence of H2, CO, NH3, NO, NO2 and C3H6 at temperatures between 100–400 °C. Significant differences in the morphology of the layer and its sensitivity were noted for different preparation methods and different gas environments.
