STUDY OF CATALYSTS TERNARY BASED PLATINUM, TIN AND MOLYBDENUM SUPPORTED IN CARBON FOR OXIDATION REACTIONS OF METHANOL AND OF ETHANOL. 2012. 55 f. Dissertação (Mestrado em QUIMICA) - Universidade Federal do Maranhão, São Luís, 2012.http://tedebc.ufma.br:8080/jspui/handle/tede/943The electrocatalytic activities of trimetallic catalysts based on platinum, tin and molibdenum, dispersed on Vulcan XC-72 carbon using an alcohol reduction method, were investigated for methanol and etanol oxidation reactions in acid solutions, with cyclic voltammetry, steady-state polarization curves and chronoamperometry. Among the catalysts Pt8Sn1Mo1/C, Pt7Sn1,5Mo1,5/C e Pt6Sn2Mo2/C investigated, the best performance was recorded on Pt6Sn2Mo2/C for the electrooxidation of metanol, as well as ethanol. In addition, such results when compared with those obtained on Pt/C sintesized by the same procedure, as well as on Pt/C-ETEK commercial sample, showed the higher electrocatalytic activity of the Pt6Sn2Mo2/C catalyst.application/pdfAcesso AbertoAtividade catalíticaReações de oxidaçãoMetanolEtanolCatalytic activityReactions OxidationMethanolEthanolCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICA::QUIMICA ANALITICADissertação
