Title of Speech: Mixed Potential Gas Sensors Combining Stabilized Zirconia with Sensing Oxide Electrodes

Abstract:

The mixed potential type gas sensor based on yttria-stabilized zirconia (YSZ) as a solid electrolyte and metal oxides as sensing electrode is considered to be a potential device for on-board diagnosis for cars. In order to enhance the sensing performance of mixed potential type gas sensors, the different composite oxide sensing materials with excellent electrochemical catalytic activity, including V, Nb and Ta system, were developed and the high performance triple phase boundary (TPB) was designed and fabricated by various strategies including HF corroding, the double-tape casting, the femtosecond laser direct writing technology and sand blasting technology. This talk is focused on the design and preparation of high performance sensing electrodes and the fabrication of high performance triple phase boundary for mixed potential type gas sensors.
