15.  DSA Type Electrodes Characterisation by Cyclic Voltammetry in the Presence of Surfactants

Authors: Monica Ihos, Gligor Bocea, Florica Manea


Abstract:

The aim of this study was surface characterisation of Ti/SnO2-Sb2O5 anode by cyclic voltammetry (CV) in the presence of nonylphenol ethoxylate with 6 ethoxy units (NP6EO). The anode was prepared by thermal decomposition of appropriate precursors. Cyclic voltammograms in 0.01 g/L NP6EO were recorded for a scan rate of 0.05 V/s and 0.1M Na2SO4 as the supporting electrolyte. The examination of the cyclic voltammograms showed that the oxidation of NP6EO could occur under conditions of simultaneous O2 evolution.


Keywords: cyclic voltammetry, DSA, nonylphenol ethoxylates
