| Popis: | In this project, the process of Pd-Co bimetallic electrodeposition on glassy carbon was studied using a choline chloride and ethylene glycol deep eutectic solvent (DES) at a temperature of 25 °C. The methodology applied for the electrochemical study comprised usual electrochemical techniques such as cyclic voltammetry (CV) and Chronoamperometry (CA). The latter showed the alloy reduction peaks, as well as the potential interval and sweep rates where a satisfactory response of the deposits was established. In addition, the type of nucleation of the alloy NPs is presented through theoretical models, as well as the value of the (apparent) diffusion coefficient, numerical density of active sites and nucleation frequency. Finally, the conclusions obtained prove that the DES used was as an optimal medium that favored the electrodeposition of the Pd-Co alloy. |
