Abstract

Electrochemical synthesis of Pd particles on poly(vinylferrocenium) (PVF+) support was described. K2PdCl4 was used as the metal particle precursor. Pd particles were incorporated into the polymer matrix electrochemically either by cyclic voltammetric scans (between +1.0 V and -0.8 V vs. SCE) or by reduction at constant potential (at -0.8 V vs. SCE) from aqueous solution of K2PdCl4. Scanning electron microscopy (SEM) studies showed that the Pd particles were well dispersed in the polymer matrix. Experimental parameters such as polymer film thickness, number of cycles during cyclic voltammetric scans in K2PdCl4 and electrolysis time in K2PdCl4 were studied. The Pd/PVF+ system showed catalytic activity towards hydrazine oxidation and appreciable results were obtained when compared with the related studies. (C) 2008 Elsevier B.V. All rights reserved.
