Many practical chemical sensors rely on catalytic surface chemistry for their operation. As a result, careful surface science under controlled conditions can often provide useful insights into sensing mechanisms. I will describe examples relating to zirconia-based electrochemical sensors for automotive nitrogen oxide detection and to silicon-carbide field-effect devices for hydrogen and hydrocarbon sensing in power-plant environments.
