A novel Ni-S-Co/ZrO2 composite electrode was prepared by electrodeposition with ZrO2 particles of 200 nm ~ 400 nm in diameter dispersed in the bath. The XRD result suggests that the Ni-S-Co/ZrO2 coating is composed of amorphous Ni , Co , S and crystalline monoclinic ZrO2 particle. The SEM images show that the coating is composed of granules with porous surface and ca. 50 m in diameter, providing high specific area. The coating is homogeneous and tightly combines with the Ni substrate with a Ni-S-Co interconnecting layer. Electrochemical tests show that the overpotential for hydrogen evolution reaction (HER) of the Ni-S-Co/ZrO2 composite electrode is 145 mV at a current density of 100 mA•cm-2 in 28% KOH solution at 25℃, which is 50 mV lower than that of the Ni-S-Co electrode. The incorporation of ultrafine ZrO2 particle into the Ni-S-Co alloy coating effectively improves the electrocatalytic activity of the Ni-S-Co electrode for hydrogen evolution reaction. The optimal conditions for electrodeposition of the Ni-S-Co/ZrO2 composite electrode are studied as well.
