This work presents the results concerning electrochemical deposition of Ni-Ru alloys from aqueous acidic solutions. The Ni-Ru coatings were obtained by the potentiostatic electrodeposition on copper porous substrates and polystyrene matrix. The influence of applied potential and concentration of electroactive species on the composition and the quality of obtained coatings was determined. The elemental composition was determined with the XRF method. X-Ray analysis has been use to determine phase composition of obtained alloys. The surface morphology was investigated with the use of scanning electron microscopy. Electrochemical measurement as a linear and cyclic voltammetry was used to perform comparative examination of catalytic properties of the obtained 3-D structures in aqueous NaOH solutions.
