Electrochemical generation of superoxide ion in ionic liquid 1-(3-Methoxypropyl)-1-Methylpiperidinium Bis (Trifluoromethylsulfonyl) Imide

In this work, the superoxide ion was generated and analysed electrochemically using cyclic voltammetry (CV) techniques from oxygen dissolved in a room-temperature ionic liquid, 1-(3-methoxypropyl)-1-methylpiperidinium bis (trifluoromethylsulfonyl) imide, at atmospheric pressure. It was found that the generated superoxide ion was stable which indicates its possible use for further useful applications. To the best of our knowledge, this is the first time a piperidinium based IL has been used for the electrochemical generation of O₂.
