✦ Synopsis
Nickel was modtfied at the surface from alkalme solution contamrng dtfferent concentrattons of WO,% or MoG4= It was shown that improvement in the overpotential (n) and in the exchange current density of the hydrogen evolution reaction m KOH 3M on the electrode depends on the nature of the heteropolyaad of the modtticetion bath. The best electrocatalyttc parameters were obtatned on electrodes mod&d with 4 gI' of W042m or 2 gP* of MOO,"
