The effect of tensioactive agents on the kinetics of hydrogen evolution at a nickel electrode

Abstract

The effect of tensioactive agents (TSA = SDS, BRIJ35, BRIJ78, BRIJ99, and CTAB) on the kinetics of hydrogen evolution at a rotating nickel electrode in 0.2 M solutions of Na2SO4 was investigated. It was found that at higher concentrations of TSA, their presence inhibited the reaction although their adsorption behaviour at the nickel electrode is different. We concluded that BRIJ35 and CTAB should show better performance in the hydrogenation of organic compounds than SDS.
