Anodic Oxygen Evolution on Iron, Cobalt and Nickel Silicides in Alkaline Electrolyte

Abstract

The kinetics of oxygen evolution reaction on iron, cobalt and nickel monosilicides in (0.1 – 5.0) M NaOH was studied using methods of polarization and impedance measurements. The values of derivatives dE/dlgi, dlgi/dpH, dE/dpH were determined. The oxygen evolution on FeSi, CoSi and NiSi electrodes in alkaline solution was established to have regularities which are characteristic to Fe, Co and Ni electrodes, respectively.
