Abstract

This work describes the development of an alternative acetate bath for the electrochemical
codeposition of Ni-Cu-Fe electrodes at low pH that is stable for several weeks and produces electrodes
with good performance for chlor-alkali electrolysis. Physical characterization of the electrode surface
was made using X ray absorption spectroscopy (XAS), scanning electron microscopy (SEM) and energy
dispersive analysis (EDX). The evaluation of the material as electrocatalyst for the hydrogen evolution
reaction (her) was carried out in brine solution (160 g L -1 NaCl + 150 g L -1 NaOH) at different temperatures
through steady-state polarization curves. The Ni-Cu-Fe electrodes obtained with this bath have shown
low overpotentials for the her, around 0.150 V at 353 K, and good stability under continuous long-term
operation for 260 hours. One positive aspect of this cathode is that the polarization behavior of the
material shows only one Tafel slope over the temperature range of 298 – 353 K.
