Such a situation requires the search for and the development of inexpensive and stable electrode materials, showing low polarization to hydrogen evolution reduction (HER).
The main objective of this work was the electrochemical preparation and characterization of the Ni and Cu oxides/hydroxides electrodeposited over stainless steel substrate, as electrocatalytic materials for HER in alkaline water electrolysis.
