Electrocatalytic activity of cobalt-molybdenum deposits is studied in the hydrogen evolution reaction (HER) in an alkaline solution.
The studied electrode materials were obtained electrochemically in the galvanostatic mode. It is shown that the rate of hydrogen evolution in 1 M NaOH at 293 K at the Co-Mo alloy is higher.
As compared to pure cobalt deposits obtained in similar conditions, which is due both to the increase of the electrode true surface area and possibly to the electronic structure of the obtained alloys.
It is established that the hydrogen reaction exchange current grows at the increase of molybdenum content in the electrode deposits in the range of 0–40 at %.
