Abstrakt: Palladium-based bimetallic electrocatalysts supported on graphene oxide were synthesized by the impregnation method, for evaluation of the formic acid oxidation reaction (FAOR) in an acid medium. The electrocatalysts were evaluated physicochemically by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques, to know the chemical composition, distribution on the support and crystal size. The evaluation of the electrocatalytic activity was carried out using the electrochemical techniques of cyclic voltammetry (CV) and chronoamperometry (CA) using the steady state current density (jss) electrochemical parameter.
