The investigation of kinetic mechanism of hydrogen evolution reaction on Hg and HgCu alloy

With the intention of improving the utilization of the electrolytic hydrogen production process, many attempts have been made to develop efficient and durable electrocatalysts for the hydrogen evolution reaction (HER) in alkaline solutions. The catalytic activity for hydrogen evolution can be enhanced by the modification of the electronic structure of electrode metals by alloying or by the use of some suitable preparation method which allows obtaining electrodes with highly developed rough or porous surfaces The purpose of the present work is to investigation of the kinetic and mechanism of hydrogen evolution reaction on HgCu alloy and also study underpotential deposition of hydrogen on these electrode.
