An alkaline silicate sol-gel approach has been established for the preparation of NASICON (sodium super ionic conductor). The prepared NASICON is characterized and used as the solid electrolyte and the base for an amperometric carbon dioxide sensor. An auxiliary electrolyte, a binary carbonate eutectic, is employed in this development. The fabrication and evaluation results of the sensor prototype are presented. Issues and future advancement of this sensor are also discussed.
