Abstract    An imidazolium based ionic liquid [BMIM][Br] was prepared, characterized and its high sensitivity behavior in the presence of gases such as oxygen, nitrogen, argon was investigated at room temperature by using impedance spectroscopy, which showed high resolution for sensing these gases. This successful study was performed with a simple experimental set up at room temperature without need to any external excitation such as photoexcitation, electromagnetic field and/or thermal excitation of the sensing material, which proves the [BMIM][Br] as a promising material for sensing such gases in industrial and medical applications. It also promisingly motivates one to study wide range of ionic liquids to make new generation of room-temperature gas sensors for such applications for sensing a wide range of gases.

 

Keywords    Ionic liquid; Impedance spectroscopy; room-temperature gas sensor; Oxygen; Nitrogen; Argon.
