The hydrogen evolution reaction on nickel-molybdenum electrodes by using potentiostatic steady state techniques has been investigated. Cathodic polarization behaviour of electrodepq ited Ni-Mo films in alkaline medium has also been studied. Further the 4:effect of cathodic polarization on electrodeposited Ni-Mo films in the;, presence of organic molecules such as maleic acid in acidic medium has also been investigated. The activity of these doped electrodes depend on the preparation and pretreatment.
