Effect of the cathode material on the accumulation of hydrogen peroxide in a plasma-solution system

The accumulation of hydrogen peroxide in a plasma-solution system with an electrolyte cathode under glow discharge action in relation to the cathode material has been studied, as well as the kinetics of the accumulation of Cu2+, Ni2+, and Ag+ ions passing from the cathode into the solution at the discharge combustion. It is shown that the Cu2+ concentration is comparable with that of the H2O2, and the use of a silver cathode results in a considerable decrease of the initial formation rate and the highest concentration of hydrogen peroxide in the plasma-solution system under study.
