Study on morphologies of palladium coated foam nickel cathodes for dechlorination of 2,4-dichlorophenol
Electrolytically deposited palladium on polypyrrole film,which is electropolymerized using potentiostatic method,covered foam nickel electrode as a support was used as cathode for the electrocatalytic hydrodechlorination of 2,4-dichlorophenol in aqueous solution.It is well known that the morphologies of polypyrrole films have dramatic influences on the dispersion of metals and the performance of the composite electrode.The influence of applied potential,temperature and polymerization time on the morphology of the films was studied by scanning electron microscopy (SEM).The fundamental electrocatalytic hydrodechlorination (ECH) results indicated that the electrocatalytic activity of Pd loaded polypyrrole foam nickel electrode is excellent for dechlorination of 2,4-dichlorophenol.The present study shows a promising choice of this kind of composite electrode for ECH.
