A new type of SPE CO2 electrochemical sensor is reported. Potential program known as anodic adsorbate stripping was used to determine the oxidation charge of reduced CO2. A satisfactory linear relation was found between Qox and the CO2 concentration. In contrast with the CO2 sensors consisting of a liquid electrolyte, the stability of SPE CO2 sensor is better. In addition, the effect of temperature on SPE CO2 sensor has been studied. This system possessed many characteristics such as compact structure, no leakage problem, better stabil...
