The influence of the aging time of RuO2 sol on the electrochemical properties of the activated titanium anodes obtained by sol-gel procedure
MetadataShow full item record
The influence of the aging time of RuO2 sol on the electrochemical properties and behaviour in chlorine evolution reaction of RuO2/Ti and (40%RuO2 + 60%TiO2)/Ti anodes obtained by sol-gel procedure was studied. The electrochemically active surface area of the anode coatings was examined by cyclic voltammetry. The electrocatalytic activity and anode stability in chlorine evolution reaction were investigated by polarization measurements and accelerated stability test. The dependence of electrochemical properties of obtained activated titanium anodes on RuO2 particle size was established.
