- W4382022002 abstract "Polypyrrole (PPy) nanoparticles were synthesized by chemical polymerization in a microemulsion system based on water, n–pentanol and sodium dodecyl sulfate (SDS) as surfactant, using pyrrole monomer and ferric chloride (FeCl3) as oxidizing agent. Additionally, PPy-fibers were obtained by adding n–decane to the polymerization system. PPy structures were characterized by scanning electron microscopy (SEM). Fourier transform infrared spectroscopy (FTIR) analysis demonstrated that polymerization in microemulsion prevented the formation of a carbonyl function associated with overoxidation of polymer chains. The presence of dodecylsulfate as doping agent was confirmed by the S=O asymmetric stretching band in PPy-nanoparticles and PPy-fibers, while sulfur concentration determined by energy-dispersive X-ray spectroscopy (EDX) can be related to the PPy doping level. The PPy-nanoparticles conductivity was higher than that of other PPy tested materials tested. This is attributed to the doping agent nature and the structure of the polymer chains. Electrocatalysts of Pt supported on the PPy structures were obtained by reduction of H2PtCl6 by means of a NaBH4 solution. Electrochemical measurements were performed in a three-electrode cell. Cyclic voltammetry results from these Pt/PPy catalysts, showed the characteristic peaks of ethanol electro-oxidation. Pt/PPy-nanoparticles presented lower charge transfer resistance (Rct) than a Pt/C catalyst. Ethanol electro-oxidation on Pt was enhanced by using nanostructured PPy as support. The PPy-nanoparticles showed better structural, conducting and electrochemical activity properties than other PPy synthesized materials tested as catalyst supports." @default.
