Abstract
TiO2 and RuO2 sols were obtained from RuCl3 and TiCl3 aqueous solutions by condensation and forced hydrolysis at elevated temperature. The Ti supported coatings were obtained by the sol–gel method using a sol mixture in which the metal content was Ru(40%)–Ti(60%). The crystal structure of the solid phase of the sols and their mixtures was examined by X-ray diffraction. The surface and morphology of the coatings were characterized by scanning electron microscopy and scanning tunneling microscopy. Polarization measurements and cyclic voltammetry were used to obtain information about the electrochemical properties of the obtained anodes. An accelerated corrosion test was applied to quantify the anode stability for the chlorine evolution reaction. A stability comparison of the anodes shows a considerably higher lifetime for sol–gel coated anodes than for those obtained by the usual thermal decomposition method.
