| 中文摘要 | in this work, we report the reverse electron transfer reaction between tcnq in 1, 2-dichloroethane (dce) and ferrocyanide in water. this process is a thermodynamic unfavorable reaction and the reverse electron transfer reaction can only be obtained by scanning electrochemical microscopy(secm) in the presence of suitable potential-determining ions, which govern the interfacial potential difference. in our case, the potential determining ions are tetrabutylammonium ion(tba(+)) and tetraphenylarsonium ion (tpas+). the effects of the concentrations of tba(+) and tpas+ in two phases and other parameters have been studied in detail. the apparent heterogeneous rate constants(k(i)) were obtained under different values of k-p(k-p=c(i)(w)/c(i)(o)) for both cases by fitting the secm approach curves with theoretical ones and the results showed that they were controlled by the interfacial potential differences. the relationship between apparent heterogeneous rate constants and the interfacial potential differences obeys butler-volmer theory. |
