Inhibitory effects of manganeous, cadmium and zinc ions on hydrogen evolution reaction and corrosion of iron in sulphuric acid solutions
Abstract
The presence of metal ions (Cd2+, Mn2+, Zn2+), more electronegative than the cathodic potential for the hydrogen evolution reaction on iron in a 0.25M H2SO4 solution, inhibits the hydrogen evolution reaction and corrosion of iron. This effect has been explained as the under-potential deposition of the adatoms of these metals on iron. © 1978.
