CO and CO2 sensing properties of electrochemical gas sensors using an anion-conducting polymer as an electrolyte

Understanding the gas adsorption kinetics of Langmuir-Schaefer porphyrin films using two comparative sensing systems

“…Acetic acid and methylamine vapors were chosen as analytes because they permit a comparison of the sensing response measured using two similar sized molecules with different functional groups. Both analytes have -CH 3 functional groups but differ in the one has a -COOH group and the other an -NH 2 group. This allows the study to investigate the influence of functional group on the sensor responses and the nature of the adsorption.…”

“…Therefore there is an increasing demand to develop new sensor devices with increased selectivity and sensitivity compared to existing sensors, ideally at lower cost. Organic materials are widely used as sensing materials with a wide range of specific subsections including polymers [3], calixarenes [4], porphyrins [5] and phthalocyanines [6]. The most important part of any adsorption sensor device is the sensing material which directly interacts with the analyte vapor.…”

CO-sensing Properties of Potentiometric Gas Sensors Using an Anion-conducting Polymer Electrolyte and Au-loaded Metal Oxide Electrodes

“…On the other hand, it is well-known that various electrochemical gas sensors using the Nafion ® as an electrolyte have also been developed and their sensing properties to some gases were really excellent even at RT [7][8][9][10][11][12], but to data electrochemical gas sensors using an ACP electrolyte have been rarely reported [13][14][15]. We have already reported that potentiometric gas sensors employing an ACP electrolyte and Pt-or Pd-loaded carbon black (CB) electrodes showed relatively large responses to CO 2 [16] or H 2 [17], respectively. In addition, we have demonstrated that the sensor employing an ACP as an electrolyte and Pd-loaded CB as an electrode also showed relatively large response to CO [18,19], but the CO selectivity of the sensor against H 2 was much lower than we expected.…”

Dye-sensitized solar cells using an anion-conducting polymer as a material of solid-state electrolyte

“…We have recently focused on anion-conducting polymers (ACP) as an electrolyte for various electrochemical devices, because of their high anion conductivity and improved longterm stability [6][7][8]. Therefore, ACP was employed as a solidstate electrolyte in fabricating DSCs, and fundamental electrochemical properties of the DSCs have been investigated in this study.…”
