Abstract

In the first period of the reaction at pH 8 slow evolution of CO2 and N2O was observed. After gas evolution ceased, on adding NaOH, formation of N2O again and, unexpectedly, H2 was found. The amount of H2 was measured as a function of reaction conditions. Illumination with visible light and the excess of the oxidant promote hydrogen evolution. The experiments in D2O resulted in H2, HD and D2. The non-statistical isotope distribution was interpreted by a kinetic isotope effect.

Abstract

В первом периоде реакции при pH=8 наблюдается медленное выделение CO2 и N2O. После понижения газовыделения добавляли NaOH, в результате чего наблюдалось повторное образование N2O и, неожиданно, H2. Количество образующегося H2 измеряли в зависимости от условий реакции. Облучение видимым светом и избыток окислителя промотировали выделение водорода. Эксперименты в D2O дают H2, HD и D2. Нестатистическое распределение изотопов объясняли кинетическим изотопным эффектом.
