dc.description.abstract
The electrodeposition of Pt and Ru on a oxidized graphite cloth from H 2PtCl6 and RuCl3 solution containing trisodium citrate (Cit), disodium tartrate (Tar) and disodium dihydrogen ethylenediaminetetraacetate (Na2H2EDTA) as complexants was investigated. SEM image of the electrode prepared without complexant showed a continuous compact and rough deposit that covers the entire graphite fibers surface displaying the structure of a coating film, whereas particles with uniform size and globular shape regularly distributed over the support were obtained when the complexants were added to the solution. Thus, EDX and XRD analysis revealed changes in Pt-Ru catalyst composition. It was concluded from electrocatalytic activity measurements that the electrodes prepared using chelating compounds exhibited better CO tolerance and performance for methanol oxidation than that without complexant. © 2011 Published by Elsevier B.V.
