Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 48 (Décembre 2012) . - pp. 15557-15563 Titre : Stability of palladium-polypyrrole-foam nickel electrode and its electrocatalytic hydrodechlorination for dichlorophenol isomers Type de document : texte imprimé Auteurs : Junjing Li, Auteur ; Huiling Liu, Auteur ; Xiuwen Cheng, Auteur Année de publication : 2013 Article en page(s) : pp. 15557-15563 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Isomer  Electrocatalysis  Electrodes  Foam  Stability Résumé : Palladium-polypyrrole-foam nickel composite electrode (Pd/PPY(PTS)/Ni) was prepared through electrodeposited of palladium nanoparticles onto preformed electrodes (surface of electrodes was coated with potentiostatic electropolymerized polypyrrole). The stability of the fresh and used composite electrode was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). It was found that the surface state, morphology, and crystalline structure of the composite electrode were stable after 5 recycle uses. Electrocatalytic activity of the composite electrode was evaluated for the hydrodechlorination (ECH) of six kinds of dichlorophenols (DCPs). Results indicated that 2,4-DCP showed higher hydrodechlorination rate. Further, the pathway of electrochemical hydrodechlorination of six kinds of dichlorophenol isomers was investigated.
