Preparation of Ru-C Nano-composite Film by MOCVD and Electrode Properties for Oxygen Gas Sensor
Kimura Teiichi,Goto Takashi 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1
Ru-C nano-composite films were prepared by MOCVD, and their microstructures and their electrode properties for oxygen gas sensors were investigated. Deposited films contained Ru particles of 5-20 nm in diameter dispersed in amorphous C matrix. The AC conductivities associating to the interface charge transfer between Ru-C composite electrode and YSZ electrolyte were 100-1000 times higher than that of conventional paste-Pt electrodes. The emf values of the oxygen gas concentration cell constructed from the nano-composite electrodes and YSZ electrolyte showed the Nernstian theoretical values at low temperatures around 500 K. The response time of the concentration cell was 900 s at 500 K.
