Electrochemical characterization of Ni-Mo-Fe composite film in alkali solution

Abstract

A composite Ni-Mo-Fe film galvanostatically coated on stainless steel substrate is studied for its electrochemical behavior in alkali solutions. The film is characterized by SEM-EDAX, ICP-AES, linear scan voltammetry and open-circuit potential decay transients. The main aim of this investigation is analyse the ternary metal coated film for its suitability as catalyst to water electrolysis. It is found that the film acts as a very good catalyst for hydrogen evolution in dilute alkali solution.
