A cell consisting of a typical 3-electrode arrangement was used with working electrode having a1 cm exposed area, an Ag / Ag Cl reference electrode as counter electrode and a platinum wire in a 3.5% wtNaClsolution.Tafel polarization curve measurements were obtained at 0.125 mV / s scan rate in a -200 mV to +1200 mV voltage range cf open circuit potential Ecorr.
Las mediciones de curvas de polarización Tafel se obtuvieron a una velocidad de barrido de 0,125 mV/s en un rango de voltajes -200 mV hasta + 1200mV vs. Ecorr.
