Correct determination of the hydrogen evolution reaction parameters at Ni foam electrode modified by electrodeposited Ni-Sn alloy layer
The example of the procedure for the correct determination of the parameters of hydrogen evolution reaction (HER), the exchange current density (jo) and relaxation time (to) for intermediate (adsorbed hydrogen, Hads) adsorption at modified porous Ni-based electrode are presented in this work. Such a...

| description | The example of the procedure for the correct determination of the parameters of hydrogen evolution reaction (HER), the exchange current density (jo) and relaxation time (to) for intermediate (adsorbed hydrogen, Hads) adsorption at modified porous Ni-based electrode are presented in this work. Such a procedure is applicable for the HER at all electrode materials. The value of jo was obtained from the intercept at h = 0 mV from the h vs. log (Rct-1) dependence (h - overpotential), while the value of to was obtained from the intercept at h = 0 mV from the logt vs. h dependence. It was shown that for the correct determination of jo and to, it is necessary to correct applied h for the jRs drop, by recording current density (j) for applied h and correcting it for jRs |
