S&M688 Research Paper of Special Issue Published: 2007 Nitrogen Oxide Gas Sensor Based on Multivalent Ion-Conducting Solids [PDF] Shinji Tamura and Nobuhito Imanaka (Received July 27, 2007; Accepted August 20, 2007) Keywords: sensor, NOx, aluminum ion, potassium nitrate, cubic rare-earth oxide
Two types of noble nitrogen oxide gas sensor were fabricated by combining Al3+-ion-conducting (Al0.2Zr0.8)20/19Nb(PO4)3 solid electrolyte and cubic rare-earth oxide-potassium nitrate solid solution as an auxiliary sensing electrode. Since the two sensors applying the oxide-anion-conducting yttria-stabilized zirconia or the aluminum metal as the reference material showed theoretical and quantitative NO gas sensing properties at 450 and 250°C, respectively, it was found that, by changing the reference material, the present sensors using the (Al0.2Zr0.8)20/19Nb(PO4)3 solid electrolyte are promising NO gas sensing devices over a wide temperature range from 250 to 450°C
