通过向溶液中添加少量的Cu 2+、AuCl 4-或Ru 3+离子，酸性溶液中Pt电极上的H2 O2的还原反应中的电流振荡的振荡周期随时间变短，而通过添加Ag+离子，周期变长。通过假设在振荡期间分散的金属原子的沉积以及金属之间的H2 O2还原机制的差异来解释这种差异。
The oscillation period of a current oscillation in reduction reaction of H2O2 on a Pt electrode in an acidic solution becomes shorter with time by addition of a small amount of Cu2+, AuCl4− or Ru3+ ions to the solution, whereas the period becomes longer by addition of Ag+ ions. The difference is explained by assuming deposition of dispersed metal atoms during the oscillation together with a difference in the H2O2-reduction mechanism among the metals.
