Abstract: The development of the electrolytes in the current-type electrochemical gas sensor is summarized. It was found that using the ionic liquid as the electrolyte has many advantages, such as non-volatilization, high conductivity, wide electrochemical window etc, compared to the aqueous solution. Combined ionic liquid with the polymer, the obtained ionic liquid/polymer electrolyte possesses both the advantages of the ionic liquid and polymer. Thus, it has the excellent application prospect. The investigation about using the organic solvent as the electrolyte in the current-type electrochemical gas sensor is just beginning. Moreover, it is also a promising route.
