我们已经证明了超氧离子可以在室温离子-液体溶剂中电化学生成。在没有杂质的情况下，循环伏安法表明超氧化物离子在这些溶剂中是稳定的。类似的超氧离子化学先前已在挥发性和环境可疑的非质子溶剂中得到证实，如二甲基甲酰胺和乙腈。然而，离子液体是非挥发性的，应该尽量减少二次溶剂浪费的问题。由此产生的超氧离子可用于废物的低温氧化。废溶剂的低温氧化可以为高温废物焚化炉提供一种急需的替代方案，高温废物焚化炉的使用因法规要求和选址合适而变得非常复杂。(C) 2001电化学学会。
We have demonstrated that superoxide ion can be generated electrochemically in room-temperature ionic-liquid solvents. In the absence of impurities, cyclic voltammetry showed that the super oxide ion is stable in these solvents. Similar superoxide ion chemistry has previously been demonstrated in volatile and environmentally suspect aprotic solvents such as dimethyl formamide and acetonitrile. However, ionic liquids are nonvolatile and should minimize the problems of secondary solvent waste. It is proposed that the resultant superoxide ion can be used to perform low-temperature oxidation of wastes. Low-temperature oxidation of waste solvents can provide a much needed alternative to high-temperature waste incinerators, whose use is greatly complicated by regulatory requirements and locating suitable sites.
