Resumen

En el presente trabajo se analizó el efecto del contenido de paladio en las nanopartículas de paladio-oro sintetizadas por un método químico para la electro-oxidación de ácido fórmico en medio ácido, a través del estudio potenciostático para obtener la densidad de corriente en estado estacionario (j_ss). La evaluación electroquímica fue realizada mediante las técnicas de voltamperometría cíclica (VC) y cronoamperometría (CA). Los electrocatalizadores obtenidos, fueron caracterizados por las Difracción de Rayos X (XRD), Microscopía Electrónica de Transmisión (TEM), Microscopía Electrónica de Barrido (SEM) y Espectroscopía de Energías Dispersivas de Rayos X (EDX).
