SOLID STATE POTENTIOMETRIC CO_2 SENSOR USING NANOCRYSTALLINE LITHIUM ION BASED ELECTRODE MATERIALS

摘要

Nanostructured bi-auxiliary phase lithium ion based potentiometric sensor for CO_2 were fabricated and investigated. The sensor showed consistent behavior in terms of Δemf/decade, absolute emf profiles thereby enhancement in response and recovery time, compared to sensor fabricated using commercial powder. The sensor was found to be stable at high temperature.
