The decomposition of alkaline hydrogen peroxide solutions at 20Β°C has been studied in the presence of both supported iron catalysts and in systems with iron initially in solution. Studies with an iron-alumina supported catalyst showed the decomposition reaction was first order with respect to total
Simultaneous hydrogen permeation and impedance measurements were carried out on iron membranes cathodically polarized at a constant current in a NaOH solution. A prolonged cathodic polarization of iron made the metal surface considerably more active for the hydrogen entry. The hydrogen permeation ra
