Kurzbeschreibung (Abstract)
The feasibility of the in situ and operando methodology in studying the chemical and electronic phenomena associated with an active metal electrode–oxide interface in metal-oxide-based gas sensors (picture) is demonstrated. It is experimentally verified that the Pt electrodes in metal-oxide based gas sensors are partially oxidised and that the oxidised Pt electrodes contribute to overall sensing performance.
