Study on the microstructure and properties of different intermediate coatings to RuO 2 -TiO 2 -SnO 2 /Ti Anodes
A normal RuO 2 -TiO 2 -SnO 2 /Ti coatings have been synthesized by a thermal decomposition method. The influence of the anodes with Ir, Ir-Co and Ir-Ta intermediate coatings is studied. The crystal phase structure and microstructure of the coatings are analyzed by XRD and SEM. The cyclic voltammetry curve and electrolytic life of anodes with different intermediate coatings are used to evaluate the electrochemical performance. The results show that cyclic voltammograms curve, chlorine evolution potential, the oxygen evolution potential and the electrolytic life change with different intermediate coatings. And the anode coating with Ir-Ta intermediate shows the best comprehensive performance.
