APPLICATION OF ION-IMPLANTATION TO ELECTROCHEMICAL STUDIES

[摘要] The application of ion implantation to electrochemical studies is illustrated with a study of electrocatalysis of the chlorine evolution reaction at RuO2, IrO2, TiO2 mixed oxide anodes in chloride solutions. Electrode/solution interfaces of well defined catalyst composition are generated in a reproducible manner by implantation of Ru (or Ir) into Ti followed by in situ oxidation of the near-surface titanium alloys. During the chlorine evolution reaction, the chlorine current is proportional to the surface concentration of the implanted impurity, and there is no surface accumulation of impurity during corrosion.
