Cyclic voltammetry and capacitance analysis of Co(SO4)2 in different cation-containing RTIL towards generation of homogeneous electron mediator |
| 초록 |
Along with the ionic liquid orientation effect at electrified interface, influence of cations in ionic liquid on the generation of an electron transfer active mediator can have added advantages towards the removal of air pollutants. In this study, [BMIM]NTF2 and [BMPyr]NTF2 ionic liquids were used for the oxidation/reduction of Co(II) by CV and impedance analyses. The initial redox behavior of Co(II) in the above two ionic liquids was identified and compared with blank. 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. |
