Artigo IPEN-doc 14503 Use of Cathorops spixii as bioindicator of pollution of trace metals in the Santos Bay, Brazil2009 - AZEVEDO, J.S.; FERNANDEZ, W.S.; FARIAS, L.A.; FAVARO, D.I.T.; BRAGA, E.S.Artigo IPEN-doc 13191 Enhanced electro-oxidation of ethanol using PtSn/CeOsub(2)-C electrocatalyst prepared by an alcohol-reduction process2008 - OLIVEIRA NETO, ALMIR; FARIAS, LUCIANA A.; DIAS, RICARDO R.; BRANDALISE, MICHELE; LINARDI, MARCELO; SPINACE, ESTEVAM V.PtSn/CeO2–C electrocatalysts were prepared by an alcohol-reduction process using ethylene glycol as solvent and reduction agent and CeO2 and Vulcan Carbon XC72 as supports. The electrocatalysts were characterized by EDX and XRD. The electro-oxidation of ethanol was studied at room temperature by chronoamperometry. PtSn/CeO2–C electrocatalyst with 15 wt% of CeO2 showed a significant increase of performance for ethanol oxidation compared to PtSn/C catalyst. Preliminary tests at 100 °C on a single cell of a direct ethanol fuel cell (DEFC) also confirm the results obtained by chronoamperometry.
