Chapter 62 The DC current that manages to cross the electrode-electrolyte interface experiences a charge transfer resistance. The expression for RCT is derived from the Butler-Volmer equation where: R is the gas constant, T is temperature (K), F is the Faraday constant, n is the number of ...
2.1.5Charge transfer resistance Investigation of charge-transfer properties is routine to examine the electrochemical performance of electrocatalysts. By conducting EIS within a reasonable frequency range, the internal/series resistance (RS) and the charge-transfer resistance (Rct) can be acquired from th...
We carefully looked at the kinetic of interfacial electron transfer process and found that the charge-transfer resistance (Rct) of TRGO/GC electrode (7.83×106Ω) was significantly lower than that of N-Gr/GC electrode (4.81×107Ω) or bare GC (1.74×109Ω). Interestingly, although TRGO/GC ...

In addition, the separation efficiency radius of the arc of electron-hole on the Nyquist plot reflects the value of reaction resistance pairs51. As shown in supplementary Table S2, the Rct value h(Rasct/a2n) and the obvious decrease with C doping, and the 10-FOC/FVOC has the ...
On the basis of Szent-Gyrgyi's recent suggestion that electron acceptors transform proteins from insulators to conductors, the possibility of charge transfer between proteins and electron acceptors and/or donors is discussed. Some problems arising in connection with the determination of the amount of ...
The serial resistance(R_S) of the cell using polymer electrolytes such as PEO, PEG, PMMA and PVAc were 21 Ω , 16 Ω , 34 Ω , and 38Ω . The charge transfer resistance (RCT) of the cell showed 61 Ω , 54 Ω , 5952 Ω , and 5232 Ω .Sung-Hae Park...
The semi-circle in the Nyquist plot was calculated to represent the charge transfer resistance (Rct). It was found that the GZnO NPs/ZnO bilayer-based photoelectrode exhibited the maximum Jsc (9.185 mA/cm) and maximum PCE (2.37%), which resulted by the minimum Rct in the device. The ...
DNAsurface chemistryThe first sequence-dependent study of DNA films containing metal-mediated base pairs has been performed to investigate charge transfer resistance (RCT) of metallo DNA. Imidazole deoxyribonucleoside (Im) has been chosen as a highly Ag(I)-specific ligandoside for the formation of ...
In the measurement, an external resistor is added in series with the working electrode to match approximately the charge transfer resistance, RCT, of the electron transfer. Extraction of RCT is then particularly simple. In addition to RCT, the uncompensated resistance, Ru, and the double layer ...
