Electrocatalysis of sandwich-structured Pd/polypyrrole/Pd composites toward formic acid oxidation / Keqiang Ding in Industrial & engineering chemistry research, Vol. 50 N° 11 (Juin 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 11 (Juin 2011) . - pp. 7077-7082 Titre : Electrocatalysis of sandwich-structured Pd/polypyrrole/Pd composites toward formic acid oxidation Type de document : texte imprimé Auteurs : Keqiang Ding, Auteur ; Haitao Jia, Auteur ; Suying Wei, Auteur Année de publication : 2011 Article en page(s) : pp. 7077-7082 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Oxidation  Composite  material  Electrocatalysis Résumé : Palladium (Pd) nanoparticle catalysts were electrodeposited onto a graphite electrode by cyclic voltammetry (CV) technique from a 0.5 M HCl solution containing 0.2 M PdCl2, and then a film of polypyrrole (PPy) was immobilized onto the as-prepared Pd-coated graphite electrode, leading to a PPy/Pd-coated electrode. Pd particles were repeatedly electrodeposited on the PPy/Pd-coated electrode to generate a Pd/PPy/Pd sandwich structured composite coated electrode. This developed composite electrode showed a satisfactory electrocatalysis toward the formic acid oxidation (FAO). The catalysis mechanism of the sandwich structured Pd/PPy/Pd composite catalyst toward FAO was also discussed on the basis of the obtained cyclic voltammograms and FT-IR spectra.
