摘　　要：离子液体作为一种新型电解质,有着优良的电化学性能,有望解决电化学气体传感器在高温、高湿下使用寿命短、稳定性差等问题。本文按照被检测气体种类对离子液体作为电解质的电流型电化学气体传感器进行了综述,就其在不同气体中的灵敏度、电化学响应、稳定性、气体传质、反应机理等方面的研究加以阐述。从灵敏度、响应时间、稳定性、选择性、抗干扰性等方面介绍了离子液体电化学气体传感器的优缺点,并对目前离子液体电化学气体传感器研究中存在的不足做了评述。同时指出未来应该加强在大气条件下电化学气体传感器性能、响应机理和电化学反应历程的研究。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.
