Stability of nanoporous silver foams in electrocatalytic dehalogenation of organic halides.

Nanoporous metal foams (NMFs) are relatively new class of nanoscale materials which consist of metals nanoparticles or filaments interconnected in such way that they form 3D structure. Such materials can be promising for creation of novel supercapacitors, heat sinks, catalysts, electrocatalysts etc. It was previously shown by us that Ag NMF fabricated by cathodic electrodeposition of Ag under high current density from acidic aqueous solutions manifested enhanced electrocatalytic activity in reactions of organic halides electroreduction compared to smooth Ag. However, for practical application of Ag NMF, their stability in the course of electrochemical processes should be evaluated.

The aim of this work was to estimate stability of Ag NMF sample in the course of electrochemical reduction of organic halides by the means of cyclic voltammetry (CV) and to compare the stability in the reactions of reduction of different organic halides.
