Electrochemical Carbon Dioxide Detection

Abstract

In this chapter, initially, the concerns about global warming and greenhouse effects, and the research on sensing, capturing, and monitoring carbon dioxide (CO2) have been discussed in a general manner. After that, the fundamental methods and electrodes used in the electrochemical measurements are given. Finally, the electrochemical detection and reduction of CO2 are detailed by potentiometric, amperometric, conductometric, voltametric, or coulometric sensors that can be utilized easily as directly as solid-state or electrolyte using types. The electrodes used as well as the measurement methods increase the variety of these sensors. From the Clark electrode to the present, Field Effect Transistors, Kelvin probes, oxygen probes, electronic noses, solid electrodes which are reinforced by using divergent nanomaterials, transition metal oxides, polymers, and porous solid electrodes were utilized in different gas sensing electrochemical methods
