Calculation of Electrochemical Parameters Starting from the Polarization Curves of Ferrocene at Glassy Carbon Electrode

Abstract

This work is a contribution to the calculation of electrochemical parameters from the polarization curves of ferrocene. The parameters are: The anodic (E pa ) and the cathodic (E pc ) peak potentials, as well as the corresponding anodic (i pa ) and cathodic (i pc ) peak currents, were obtained at different scan rates (0.05, 0.10, 0.30, 0.50 V.s -1 ). The half-wave potentials (E 1/2 ) of the couple in the investigated solvents have been evaluated. The diffusion coefficients (D) have been calculated using the Randles-Sevcik equation.

Tris(ferrocenylmethidene)sumanene: synthesis, photophysical properties and applications for efficient caesium cation recognition in water

“…19b For comparison, we obtained the coefficient diffusion of native Fc in DCM which is 7.72 × 10 −5 cm 2 s −1 . 20 The diffusion coefficient describes the diffusional transport and is an important parameter of the species that are involved in the electrochemical process. The comparable diffusion coefficient values for 3 and native Fc testify to the lack of a significant effect of sumanene on the mobility of its derivative with Fc.…”

“…8). [30,31] It was confirmed the addition of Cu 2+ results electron transfer redox (oxidation-reduction) process. The anodic peaks for 4MHEB-Cu 2+ ion appeared at Epa = -0.0242 V and cathodic peak Epc = +0.3027 V while anodic peak at Epa = -0.1470 V and cathodic peak Epc = +0.5890 V for 4MHEB.…”

Comparative study of water‐processable polymeric binders in LiMn2O4 cathode for aqueous electrolyte batteries

“…[ 21,38 ] Additionally, the ratio of the anodic and cathodic current peak heights is close to one for PTFE, PTFE+CMC, SBR, and SBR+CMC, which reflects the reversible nature of the reaction. [ 39 ] The slopes of each line were used in conjunction with the Randles‐Sevcik equation, shown below in Equation (1), to determine the apparent diffusion coefficient for LiMn 2 O 4 in each electrode.
