Voltammetric behaviour of H2O2 in strong alkaline medium on platinized platinum

Abstract

The voltammetric curves of H₂O₂ in de-aerated 1N NaOH solutions obtained with an electrode with periodical renewal of the diffusion layer show that the electro-reduction of H₂O₂ to H₂O on platinized platinum proceeds through the purely chemical decomposition of H₂O₂ and the simultaneous reduction of O₂ so formed to H₂O₂. These conclusions are supported by the analysis both of current-time curves and current-potential characteristics.
