Performance of Pd electrocatalyst supported on a physical mixture indium Tin oxide–carbon for glycerol electro– oxidation in alkaline media. <b>Electroanalysis</b>, v. 29, p. 1-6, 2017.

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.1-6closedAccesselectrocatalystspalladiumindium oxidestin oxidesglycerolcarbon oxidesdirect ethanol fuel cellsalkali metal compoundsoxidationArtigo de periódico2910.1002/elan.201600569https://orcid.org/0000-0002-9287-6071https://orcid.org/0000-0002-7011-826164.41
