    摘要： PROBLEM TO BE SOLVED: To provide a method for simply producing clean hydrogen peroxide at a low cost without giving a large load on the environment.
    SOLUTION: The method comprises adding a catalyst comprising metal oxide particles and gold nanoparticles supported on the surfaces thereof to water and sending an oxygen gas. Preferably, the metal oxide is at least one oxide selected from among a silica-alumina double oxide, zeolite, silica, alumina, titania, iron (III) oxide, beryllia, and magnesia. The gold nanoparticles preferably have a diameter of 2 to 10 nm with a standard deviation of 1 nm or smaller.

    摘要： PROBLEM TO BE SOLVED: To provide an electrolytic cell which prevents metal deposition to an anode surface and prepares a hydrogen peroxide at an adequate current density and an electrolytic method. SOLUTION: Polyvalent method ions are removed by an apparatus 10 for removing the polyvalent metal ions and dissolving a low-concentration salt and the raw material water prepared by dissolving the univalent metal salt, such as sodium sulfate, at a prescribed concentration is supplied to the electrolytic cell 1. Since the polyvalent metal ions do not exist in the electrolyte in spite of continuation of the electrolysis and therefore there is substantially no deposition of the hydroxide and carbonate to the cathode and the sufficient current density is assured by the dissolved salt. The stable preparation of the hydrogen peroxide for a long period is thus made possible without the exertion of an excessive burden on the electrodes, etc.

    摘要： PROBLEM TO BE SOLVED: To provide a miniaturized hydrogen peroxide generating apparatus. SOLUTION: In an apparatus generating hydrogen peroxide by electrifying in a cathode 10 and an anode 3, an electroconductive material 17 is installed inside of a container 1. An anode box 2, in which the anode 3 is installed, can be attached to and detached from the container 1 easily and freely. Outside of the anode box 2 in the container, the cathode 10 is installed and an oxygen containing water 6 is put. A membrane 5 is also installed at a part of the anode box 2 and between the anode 3 and the cathode 10 so as to pass current between both the electrodes.
