The hydrogen evolution reaction on electrodeposited NiMo alloy coatings, as well as
their electrochemical properties in NaOH solutions have been investigated by polarization
measurements, cyclic voltammetry and EIS technique. It is shown that NiMo alloy coatings
electrodeposited from pyrophosphate-sodium bicarbonate bath possess high catalytic activity for
hydrogen evolution in NaOH solutions. Their stability in 1M NaOH at 25 0C under the condition
of reverse polarization is shown to be very good, while in 33% NaOH at 850C (conditions of
industrial electrolysis) electrodeposited NiMo alloy coatings exhibit also high catalytic activity,
but low stability, as a consequence of massive dissolution of alloy coatings under the condition
of reverse polarization.
