Abstract
Tin dioxide nanocrystals were synthesized by a precipitation process and then used as the support for 2 wt.% gold/tin dioxide preparation via a deposition–precipitation method, followed by calcination at 200 °C. Thick films were fabricated from gold/tin dioxide powders, and the sensing behavior for carbon monoxide gas was investigated. The gold/tin dioxide was found to be efficient carbon monoxide gas-sensing materials under low operating temperature (83–210 °C). The Au/SnO2 sensor with SnO2 calcined at 300 °C exhibited better CO gas-sensing behavior than the SnO2 calcined at other temperatures. The experimental results indicated the potential use of Au doped SnO2 for CO gas sensing.
