| Description |
Ni–Mn–S was electrodeposited on mild steel from sulphate–thiocyanate baths. The resultant
materials were evaluated for electrocatalytic activity towards hydrogen evolution reaction in
30 wt-% KOH. Incorporation of sulphur in Ni–Mn improves the electrocatalytic activity giving a
sizeable increase in exchange current density j0. In Ni–Mn the hydrogen evolution reaction is
through a Volmer–Tafel mechanism whereas in the Ni–Mn–S system follows a Tafel mechanism.
The influence of deposition current density (CD) was investigated. Electrocatalytic activity
increased with increase in the deposition CD and was maximum in samples deposited at
80 mA cm22.
