THE ELECTROCHEMICAL-BEHAVIOR OF IRIDIUM DIOXIDE MODIFIED BY ION-IMPLANTATION

Thermolytic iridium oxide films whose surface was modified by ion impl antation of argon and oxygen ions are investigated electrochemically. Ion implantation is shown to be accompanied by changes in the space ch arge constituents and the emergence in the electrode surface layer of new active centers brought about mainly by radiation modification. The increase in the catalytic activity in the oxygen evolution reaction a t doped electrodes is shown to correlate with a part of the surface ch arge.
