摘要： PROBLEM TO BE SOLVED: To provide a chemical which simultaneously produces hydrogen peroxide and hypohalide ions and is particularly suitable for seawater treatment. SOLUTION: In the electrolytic cell in which an anode chamber for holding an insoluble anode which can oxidize halide ions and a cathode chamber for holding a gas diffusion cathode which can oxidize an oxygen-containing gas to produce hydrogen peroxide are devided with at least one membrane, electrolysis is performed by feeding halide ion-containing water to the anode chamber and an electrolytic solution to the cathode chamber. In this way, a hypohalide is produced in the anode chamber, and hydrogen peroxide is produced in the cathode chamber, respectively. By suitably setting electrode substances and electrolytic conditions, hydrogen peroxide and the hypohalide are simultaneously produced differently from the conventional case so that the cost of electric power and the cost incidental thereto can remarkably be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a method which is capable of manufacturing hydrogen peroxide water not containing organic halogen compounds by solving such a problem heretofore that harmful organic halogen compounds have been included in the hydrogen peroxide water exerting an adverse influence on the environment when the hydrogen peroxide water is manufactured by seawater electrolysis. SOLUTION: A branched seawater is subjected to various kinds of treatment, such as mechanical separation by a strainer, separation after flocculation of floc, etc., in the seawater, chemical separation of the seawater like activated carbon treatment and decomposition by irradiation with UV rays, by which the organic compounds in the branch seawater are removed and thereafter the branch seawater is supplied to an electrolytic cell to which gaseous oxygen is supplied. The gaseous chlorine and hypochlorous acid ions occurring in the chlorine ions in the seawater are formed in the electrolytic cell but the organic compounds which are raw materials do not exist and therefore the organic halogen compounds are not formed and the hydrogen peroxide water not containing the harmful component can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for electrolytic production of high-purity hydrogen peroxide water to be used for a washing treatment, etc., of electronic devices and liquid crystals. SOLUTION: At the time of forming atomic hydrogen in an electrolytic cell in which an anode 7 and a cathode 8 consisting of a hydrogen occlusion metal and/or alloy (more preferably palladium and palladium alloy) is housed and forming hydrogen peroxide by reducing the oxygen by the device, the anode and the cathode are segmented by using an ion exchange membrane 2 functioning as a solid electrolyte. As a result, the need for dissolving the electrolytic substance into the electrolyte is eliminated and the intrusion of the anodic substance into the hydrogen peroxide water to be formed is prevented and therefore, the hydrogen peroxide water of the high-purity free from the intrusion of impurities may be provided.

摘要： PROBLEM TO BE SOLVED: To solve a problem that the performance of a tabular electroconductive diamond electrode is degraded due to the production of a carbonaceous substance having a non-diamond structure on one side, when the electrode is produced by using a CVD technique, and consequently to keep the performance of the electrode high by activating the electrode.
SOLUTION: This activating method includes bringing the surface of the electroconductive diamond electrode in contact with at least one substance selected from among excited hydrogen, excited oxygen and excited argon. The carbonaceous substance of the non-diamond structure produced on the surface contacts the excited gas, and is removed from the surface of the electrode.

摘要： PROBLEM TO BE SOLVED: To provide an oxygen reducing gas diffusion cathodes capable of being used under a severe operation condition through a long period in a sodium chloride electrolysis in which the electrode performance is apt to degraded because a catalyst particle supported by a base material of a gas diffusion cathode is dipped in an elecrtrolyte and a sodium chloride electrolytic method using the oxygen reducing cathode. SOLUTION: The oxygen reducing gas diffusion cathode comprises a porous conductive base material, a diamond particle having a hydrophobic surface and the catalyst particle which are formed on the porous conductive base material. The gas supply is smoothly carried out because a network is formed on the surface of the base material by the hydrophobicity of the diamond particle and the degradation of the electrode due to the active oxygen species is suppressed because the whole electrode is made hydrophobic and then, the long term stable operation is carried out.

摘要翻译：解决的问题：提供一种氧化还原性气体扩散阴极，其能够在氯化钠电解中长时间在苛刻的操作条件下使用，其中电极性能易于劣化，因为由使用氧还原阴极将气体扩散阴极的基材浸渍在电解液和氯化钠电解方法中。解决方案：氧还原气体扩散阴极包括多孔导电基材，形成在多孔导电基材上的具有疏水性表面的金刚石颗粒和催化剂颗粒。由于通过金刚石颗粒的疏水性在基材的表面上形成网络，所以气体供给平稳地进行，并且由于整个电极被制成疏水性，所以抑制了由于活性氧引起的电极的劣化，长期稳定运行。版权所有（C）2007，JPO＆INPIT
