The synthesis process of Co–Ni alloy nanoparticles via electroless deposition in ethylene glycol (EG) was electrochemically investigated. Insufficient thermodynamic data for organic solvents prevented us from calculating the oxidation–reduction (redox) potentials Co(II)/Co and Ni(II)/Ni redox pairs solvents. In present work, however, EG were determined by using voltammetry combined with quartz crystal microbalance. cyclic voltammograms, current cobalt on substrate much higher than that nickel substrate, which resulted decreasing particle size increasing amount. Moreover, it experimentally clarified a mixed potential each partial reaction. Specifically, hydrazine oxidation reaction dominant this system, is key to controlling potential.
