Method and device for conversion of water into hydrogen peroxide

A device for converting water into hydrogen peroxide (H2O2), the device comprising:

• a hollow body containing toward an upper end thereof a pair of electrodes one of which is insulated and another of which is not insulated and wherein a respective surface of each of the electrodes face one another across a gap between said surfaces such that when a high AC voltage is applied across the electrodes a corona discharge zone is generated in the gap,
• a first one of the electrodes being disk-shaped and concentrically fastened to an axle that is formed of electrically conductive material and is rotatably coupled to a shaft of an electric motor mounted in the upper end of the body,
• a second one of the electrodes being mounted on an insulator and being configured for connection thereto of a high voltage output of a AC voltage generator,
• an outer diameter of the first electrode being larger than an outer diameter of the second electrode,
• a water container in a lower end of the body,
• an H2O2 outlet intermediate the water container and the electrodes for removal of H2O2 outside the device,
• a water inlet in said hollow body for supplying water to the container, and an electrical terminal located inside the body toward the lower end thereof and configured for connecting a low voltage output of the AC voltage generator;
• wherein
• liquid water is conveyed on to a surface of the first electrode facing the second electrode close to the axis of rotation of the first electrode whereby the liquid water advances outward through the corona discharge zone towards a periphery of the first electrode under the action of centrifugal force caused by rotation of the first electrode.
