Ionic liquids,as a new type of electrolyte,are expected to solve the problem of short life, poor stability of electrochemical gas sensors at high ambient humidity and temperature. The applications of ionic liquids as electrolyte solution in electrochemical gas sensors were reviewed according to the species of the gases. The studies on sensitivity,electrochemical response,stability, gas mass transfer and reaction mechanism of different gases were presented. The advantages and disadvantages of ionic liquid electrochemical gas sensors were discussed from the aspects of sensitivity,response time,stability,selectivity and anti-interference. The imperfections of current research on ionic liquids in electrochemical gas sensor were introduced. Moreover,future research on electrochemical gas sensors was suggested. Under atmospheric condition,the study on properties of sensors,response mechanism and electrochemical reaction process should be emphasized in the future.
