Abstract:  The possibility of producing hydrogen peroxide by cathodic reduction of oxygen in solutions of potassium or sodium hydroxide was examined. It was shown that on porous cathodes prepared from commercial active carbons or from powdered electrographite, the current yields of hydrogen peroxide were nearly zero or too low for practical purposes. Further it was found that the current yields may be markedly enhanced by heating active carbon with sulfur compounds, e.g. potassium or sodium sulfide, before preparing the electrodes. Various dependences of current yields and cell voltage on the individual reaction conditions are given.
