In situ DRIFT study of hydrogen and CO adsorption on Pt/SiO2 model sensors
Paper i proceeding, 2007

The sensing mechanism towards carbon monoxide of Metal Insulator Silicon Carbide (MISiC) Field Effect devices used as sensors, has been studied by in situ FTIR spectroscopy in diffuse reflectance mode (DRIFT). The infrared studies were performed using a model sensor, where adsorption of CO in presence of oxygen and hydrogen has been studied. The results show that the CO adsorption on Pt varies with varying oxygen concentration, CO concentration, hydrogen exposure and temperature. When correlating the DRIFT spectroscopy with sensor signal measurements, the CO response or MISiC field effect devices appears to be connected to the CO coverage of the sensor surface.
