Palladium electrocatalysts, supported on Vulcan XC 72 carbon and indium tin oxide (ITO) with different ratios, were prepared by borohydride reduction method and analysed for glycerol electro-oxidation application in the presence of KOH solution. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) techniques were used to characterize the particle size and crystal electrocatalyst structures, whereas their catalytic activities regarding the glycerol electro-oxidation were evaluated by cyclic voltammetry (CV), chronoamperometry and tested in a direct alkaline glycerol fuel cell (DGFC) by electrochemical techniques. Micrographs results showed that the ITO presence promotes a large agglomeration of particles. Pd/C???ITO electrocatalysts showed peaks associated with the face-centered cubic (fcc) structure of palladium and several others peaks associated with ITO used as support. Similar performance was found on all Pd/ C???ITO electrocatalysts where measurements in CV were compared to Pd/C and Pd/ITO with Pd/C???ITO 50:50 chronoamperometry, presenting a better performance for glycerol electro-oxidation. When using Pd/C???ITO 85:15 electrocatalyst and 1.0 mol L 1 glycerol at 908C, the maximum power density found was 2,1 times higher than that obtained using Pd/C and Pd/CITO electrocatalysts. Therefore, the physical mixture of ITO and carbon, to be used as a support improves the electrocatalytic activity for glycerol oxidation reaction.Funda????o de Amparo ??
