In this study, electrochemical nitrate-ion sensors based on Cu-based spinel-type oxide thick-films have been investigated. Spinel-type oxide fine powders prepared by a polymer precursor method at 550℃ were used for screen printing to prepare thick-film devices. Among the spinel-type oxides tested, the CuCo2O4-based device showed relatively good amperometric response to nitrate-ion between 1.0×10-4 and 1.0×10-2 M at pH = 5 among the tested NO3-. Cl-, and H2PO4-. The 90% response time of the sensor device was as short as about 30 s at room temperature.本誌: 電気学会論文誌E（センサ・マイクロマシン部門誌） Vol.142 No.11 （2022） 特集：環境・生体情報の可視化・リアルタイムモニタリング本誌掲載ページ: 308-309 p原稿種別: 研究開発レター／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejsmas/142/11/142_308/_article/-char/ja/ Show more
