Electrode Materials For Hydrogen Energy

Abstract

Regularities of cathodic hydrogen evolution on composite electrolytic coatings with Co-Mo-WOx, Co-Mo-ZrO2 and Co-W-ZrO2 alloys are established. The kinetic parameters of the reaction of hydrogen evolution on cobalt alloys, such as the slope coefficients of the Tafel dependences, transfer coefficients, and exchange currents, have been determined. A mechanism for hydrogen evolution on cobalt composite alloys is proposed. The synthesized composite coatings can be recommended as active layers for electrodes used in hydrogen synthesis.
