Die Inhibition der Sauerstoffreduktion durch dünne Ni(OH)2-Filme

Inhibition of oxygen reduction by thin Ni(OH)₂ films During the cathodic reduction of oxygen in Ni²⁺-contending solutions thin Ni(OH)₂-layers can be precipitated. These layers inhibit the electrode reaction. During stationary measurements the current density is equal to the limiting diffusion current density of the hydronium ions, which is necessary for the stabilization of the layer in the non-saturated electrolyte. The thickness of the layers can be calculated with Faraday's law.
