摘要：

Nickel was modified at the surface from alkaline solution containing different concentrations of WO42- or Mo0(4)2-. It was shown that improvement in the overpotential (eta) and in the exchange current density of the hydrogen evolution reaction in KOH 3M on the electrode depends on the nature of the heteropolyacid of the modification bath. The best electrocatalytic parameters were obtained on electrodes modified with 4 gl-1 of W0(4)2- or 2 gl-1 of Mo0(4)2-.
