循环铱、铑或钌的电位可导致电极表面金属氧化物的生长。氧化层的形成取决于循环的电位上限和下限以及电解质溶液的组成。氧化物中金属原子的价的可逆变化，伴随着质子转移，在电位循环中发生，并产生围绕电位轴对称的伏安峰。讨论了氧化物的性质、组成及其析氧电催化活性。
Cycling the potential of iridium, rhodium or ruthenium can result in the growth of a metal oxide on the electrode surface. The formation of the oxide layer depends on both the upper and lower potential limits of the cycle and on the composition of the electrolyte solution. Reversible changes in valency of the metal atoms in the oxide, accompanied by proton transfer, occurs during a potential cycle and give rise to voltammetric peaks which are symmetrical about the potential axis. The nature and composition of the oxides and their electrocatalytic activity for oxygen evolution are discussed.
