Journal ArticleDOI
Carbon-supported ternary PtSnIr catalysts for direct ethanol fuel cell
Josimar Ribeiro,D. M. dos Anjos,D. M. dos Anjos,Kouakou Boniface Kokoh,Christophe Coutanceau,J.-M. Léger,Paulo Olivi,A.R. de Andrade,Germano Tremiliosi-Filho +8 more
TL;DR: In this article, TEM and XRD results showed that the electrocatalysts consisted of the Pt displaced phase, suggesting the formation of solid solutions between the metals Pt/Ir and Pt/Sn.
Journal ArticleDOI
Electroactivity of tin modified platinum electrodes for ethanol electrooxidation
F.C. Simões,D. M. dos Anjos,Fabrice Vigier,J.-M. Léger,Françoise Hahn,Christophe Coutanceau,Ernesto R. Gonzalez,Germano Tremiliosi-Filho,A.R. de Andrade,Paulo Olivi,Kouakou Boniface Kokoh +10 more
TL;DR: In this paper, a single direct ethanol fuel cell (DEFC) was used to evaluate the catalytic activity of various compositions of PtSn electrodes prepared by thermal decomposition for ethanol electrooxidation.
Journal ArticleDOI
Electrooxidation of glyphosate herbicide at different DSA® compositions : pH, concentration and supporting electrolyte effect
S. Aquino Neto,A.R. de Andrade +1 more
TL;DR: In this paper, the authors investigated the electrochemical oxidation of glyphosate herbicide (GH) on RuO 2 and IrO 2 dimensionally stable anode (DSA ® ) electrodes.
Journal ArticleDOI
Activity of platinum–tin catalysts prepared by the Pechini–Adams method for the electrooxidation of ethanol
F.L.S. Purgato,F.L.S. Purgato,Paulo Olivi,J.-M. Léger,A.R. de Andrade,Germano Tremiliosi-Filho,Ernesto Rafael Gonzalez,Claude Lamy,Kouakou Boniface Kokoh +8 more
TL;DR: Pt-Sn electrocatalysts of different compositions were prepared and dispersed on carbon Vulcan XC-72 using the Pechini-Adams method as mentioned in this paper, which showed that the presence of Sn greatly enhances the activity of Pt towards the electrooxidation of ethanol and contributes to reduce the amount of noble metal in the anode of direct alcohol fuel cells.
Journal ArticleDOI
Effect of W on PtSn/C catalysts for ethanol electrooxidation
Josimar Ribeiro,D. M. dos Anjos,D. M. dos Anjos,J.-M. Léger,Françoise Hahn,Paulo Olivi,A.R. de Andrade,Germano Tremiliosi-Filho,Kouakou Boniface Kokoh +8 more
TL;DR: In this article, the Pechini-Adams modified method on carbon Vulcan XC-72 was used for the preparation of ternary Pt-based catalysts for ethanol fuel cell.
