Paper Title:
Effect of Supported Transition Metal on CO Sensing Performance Using SnO2 in Reducing Atmosphere
  Abstract

CO sensing properties of various transition metal oxide-loaded SnO2 sensors were investigated in a reducing atmosphere such as wet H2 gas. Among transition metal oxide-loaded SnO2 sensors used in the present study, 5wt%CuO-loaded SnO2 sensor exhibited the highest sensitivity to 1% CO in wet 50% H2 at around 150 °C, while it showed no sensitivity in dry 50% H2. From XRD analysis, CuO was reduced to metallic Cu in a reducing atmosphere at above 150 °C. H2-temperature-programmed reduction (H2-TPR) and diffuse reflectance fourier transform infrared (DRIFT-IR) spectroscopy measurements were carried out to discuss the sensor response mechanism.
