Effect of cation-containing RTIL on the Co(II) redox behavior towards homogeneous electron mediator generation |
| 초록 |
In addition to the orientation analyses of pure ionic liquids on an electrode surface, disclosure of the cationic effect of an ionic liquid in the generation of an electron transfer active mediator can have added advantages towards the removal of air pollutants. In this study, 1-butyl-3-methylimidizolium-bis-trifluoromethylsulfonylimide ([BMIM]NTF2) and 1-butyl-3-methylpyrrolidinium-bis-trifluoromethylsulfonylimide [BMPyr]NTF2 ionic liquids were used for the oxidation/reduction of Co(II) by cyclic voltammetry and impedance analyses. The initial redox behavior of Co(II) in the above two ionic liquids was identified and compared with that of the pure ionic liquids. The [BMPyr]NTF2 ionic liquid showed stronger adsorption on a Pt electrode than [BMIM]NTF2. The charge transfer resistance (RCT) during the oxidation of Co(II) was determined to be higher in the [BMPyr]NTF2 ionic liquid. No capacitance variations with the applied potential in a [BMIM]NTF2 ionic liquid but the [BMPyr]NTF2 ionic liquid showed a negative charge below -1.0 V and a positive charge beyond -1.0 V. Finally, derived conclusion will be discussed. |
