摘要

A miniaturized electrochemical carbon dioxide (CO2) sensor using Na3Zr2Si2PO12 (NASICON) as a solid electrolyte has been fabricated and demonstrated. Microfabrication techniques were used for sensor fabrication to yield a sensing area around 1.0 mm × 1.1 mm. The NASICON solid electrolyte and the Na2CO 3/BaCO3 (1:1.7 molar ratio) auxiliary electrolyte were deposited by sputtering in between and on top of the interdigitated finger-shaped platinum electrodes. This structure maximizes the length of the three-phase boundary (electrode, solid electrolyte, and auxiliary electrolyte), which is critical for gas sensing. The robust CO2 sensor operated up to 600°C in an amperometric mode and attempts were made to optimize sensor operating parameters. Concentrations of CO2 between 0.02% and 4% were detected and the overall sensor performance was evaluated. Linear response of sensor current output to ln[CO2 concentration] ranging from 0.02% to 1% was achieved. copyright The Electrochemical Society.
