Abstract
In the present work, the kinetic parameters from the electrodeposition of bimetallic Pd-Ni nanoparticles on the surface of a glassy carbon electrode (GCE) were studied. These parameters are P1 directly related to the diffusion coefficient (D), P2 related to the numerical density of active sites (N0) and the nucleation frequency (A). In addition, the type of nucleation that occurs in electrodeposition, instantaneous or progressive. The electrolytic medium used was an ethaline deep eutectic solvent (DES) for electrodeposition due to its good electrochemical properties. Cyclic voltammetry (CV) and potentiostatic current density transients (j-t) were performed at two temperatures, 25 and 70 °C. The j-t values were used to generate theoretical fittings using the Scharifker and Hills, and the Díaz-Morales models for bimetallic phases.
