発明の概要(英語) This composite comprises: a material having electrical conductivity; and a transition metal oxide which is supported by said material. The transition metal oxide has an amorphous structure.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, in order to reduce the carbon dioxide can be used for renewable energy have been studied. Such as solar power and wind power as renewable energy produced from the secondary battery is difficult, the excess energy generated from renewable energy as a means for stocking, hydrogen or ammonia, methylcyclohexane is used as a carrier energy and the like have been proposed. In any case the excess energy from the hydrogen needs to be obtained. Efficiently as a method to obtain hydrogen, a hydrocarbon such as from a fossil fuel steam reforming method or the like has been known a method for obtaining hydrogen. However, in a case where the global environmental problems, fossil resources as possible to obtain hydrogen by a method not depending on the important.
Such as, electrolysis reaction of water is known. Electrolysis of water using fossil fuels as the steam reforming method or the like, industrial method for producing hydrogen is established, the rise of the hydrocarbons and petrochemical by steam reforming method which is economically advantageous. Under such circumstances, the industry as a method for producing hydrogen by electrolysis in order to use, high temperature and high pressure water electrolysis, the electrolyte of the solid polymer electrolyte (Solid Polymer Electrolytes, SPE), such as high temperature steam electrolysis has been the development of the technology.
The voltage of the electrolytic bath of water, the electrolytic voltage theory, due to the resistance of a reaction in the electrode overvoltage, and the electrical resistance of the membrane electrolyte by adding the ohmic losses. Theoretical electrolytic voltage is, the amount of electricity for the electrolysis and the enthalpy change and the amount of electricity required for the (1.23V) is obtained from the voltage and the like. Of the water in order to reduce the voltage of the electrolytic cell, the electrolytic voltage of the theoretical, reducing any of the overvoltage and ohmic losses can be considered. This can also be obtained from the calculation of the theoretical one in the electrolytic voltage is, the optimum value by changing the design of cell ohmic losses can be obtained, the ability to promote the electrochemical reaction overvoltage a strong catalytic activity can be lowered by using a higher electrode can.
Is Patent Document 1, the iridium oxide catalyst was used and the electrolysis of water at the anode, a cathode with generated protons, alcohol and a carboxylic acid at the cathode to generate hydrogen has been disclosed a technology.
Non-Patent Document 1 is, the obtained electrodeposited the electronic structure of the iridium oxide film was examined, the electrolysis of water during the reaction between Ir of the Ir (III) oxidation state (V) the presence of both the clear.
Is in Non-Patent Document 2, firing at 500°C the iridium oxide generated (T-IrO2), which are obtained by further 500°C reduction of the iridium (A-Ir), which is obtained by electrochemical oxidation in the E-Ir, the performance was evaluated as the anode has been described. According to this, the oxygen evolution reaction occurs in a region where the Ir (III) is present, Ir (III) is, in the E-Ir and the T-IrO2 E-Ir is preferable that, the E-Ir amorphous and, Ir atoms in the porous surface of a large exposure has been described.
