RESEARCHES ON THE INFLUENCE OF SOME MINOR CONSTITUENTS OF THE SOLUTION ON HYDROGEN OVERVOLTAGE OF CU SINGLE CRYSTALS
Abstract
The influence of 10 to the -5th power M/l of Cd and 10 to the -4th power M/l of As, Sb, and In in 0.1M H2SO4 on the H overvoltage of Cu polycrystalline and single crystal cathodes, oriented following the (111), (110), and (100) planes, was investigated. In the cd range studied, due to the presence of Cd and In, the Tafel line was broken into two branches, shifted one from the other, having almost the same b value. In the presence of Sb, or As, the overvoltage vs log cd plot remained linear, but the slope value for As is lower. (Author)
