Abstract:
Nanocrystalline SnO2 has been synthesized and its surface has been modified with Au-0 and Co(II, III). The distribution of the modifiers over the nanocomposites has been studied by X-ray diffraction, inductively coupled plasma mass spectrometry, and transmission electron microscopy. The effect of the modifiers on the hydrogen reduction of nanocrystalline SnO2 has been assessed. The CO sensing properties of the synthesized materials (10 ppm CO in air) have been studied in situ by electrical conductance measurements. The addition of both Au-0 and Co(II, III) allows the working temperature of the SnO2-based semiconductor sensor to be lowered to 215A degrees C.
