PREPARING ANODES WITH HIGH EFFECTIVE CATALYTIC SURFACE AND THEIR ELECTROCHEMICAL BEHAVIOR IN THE CHLORINE EVOLUTION REACTION

By anodizing of titanium and then electroplating of Platinum on surface anodized titanium، electrodes with high effective surface catalytic were made. Consideration of surface morphology using scanning electron microscope (SEM) shows that، with anodizing، micro porous layer on titanium surface was prepared. The electro catalytic behavior of this type of electrodes in the isopropanol electro oxidation and in the chlorine evolution reaction was studied. Comparison of electro catalytic activity of this type of electrodes with platinum electrodes shows that، these electrodes have more than electro catalytic activity of platinum electrodes. Thereby we can use of this type of electrodes in chloro-alkaline industry as a suitable anodes.
