Cathodic evolution of hydrogen on carbides of iron-family metals

The activity of carbides of iron-family metals with respect to hydrogen evolution in acidic solutions is found to be much higher than the activity of the corresponding metals and increase in the sequence Ni 3 C < Co 3 C < Fe 3 C. Of the carbides studied, cementite has the highest activity, whi...

Description
Summary:	The activity of carbides of iron-family metals with respect to hydrogen evolution in acidic solutions is found to be much higher than the activity of the corresponding metals and increase in the sequence Ni 3 C < Co 3 C < Fe 3 C. Of the carbides studied, cementite has the highest activity, which is comparable to that of a Pt electrode.
