Resumo
Pd/C-ITO and PdMn/C-ITO electrocatalysts with different atomic ratio (90:10, 70:30 and 50:50) were
synthetized by borohydride reduction method and characterized by X-ray diffraction, Transmission
electronic microscopy and electrochemical studies (cyclic voltammetry). The electrochemical studies
showed that PdMn(50:50)/C-ITO had superior performance for electrochemical oxidation of methane
in an acidic electrolyte at 25 oC compared to others electrocatalysts prepared. The experiments in a
single DMEFC also showed that the PdMn(70:30)/C-ITO electrocatalyst exhibited higher performance
for methane oxidation in comparison with Pd/C-ITO, PdMn(90:10)/C-ITO and PdMn(50:50)/C-ITO
electrocatalysts. These result indicated that the addition of Mn to Pd favor the electrochemical
oxidation of Methane in acid medium, where this effect could be attributed to the synergy between
the constituents of the binary electrocatalysts or to electronic modification of Pd atoms by the
neighboring Mn atoms as the proximity of Pd and Mn atoms on the surface of the C-ITO (bifunctional
mechanism - the presence of Pd and Mn oxides species).
