Electrodeposition of Functional Ni-Re Alloys for Hydrogen Evolution

The aim of this work was to obtain Ni - Re binary alloy by a simple method of electrodeposition. Nickel - rhenium alloys have been deposited from nickel sulfamate and ammonium perrhenate electrolyte with citrate-anion additives. The effects of bath temperature, current density, bath composition and influence of magnetic field were studied. The impacts of these parameters on hydrogen evolution process for obtained Ni - Re alloys were examined. The deposited layers were determined by optical and scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray fluorescence (XRF).
