発明の名称 (英語) CATALYST, ELECTRODE, WATER ELECTROLYSIS METHOD, AND METHOD FOR PRODUCING CATALYST NEW 新技術説明会
発明の概要(英語) A catalyst according to the present invention is characterized by being configured from a material that contains a metal sulfide and β-C3N4. It is preferable that nickel sulfide is contained as the metal sulfide. It is particularly preferable that NiS and Ni3S2 are contained as the nickel sulfide. It is also preferable that the overvoltage required for oxygen production at a current density of 10 mA/cm2 is 150 mV or less. The present invention is able to provide: a catalyst having high catalytic activity; an electrode which contains a catalyst having high catalytic activity; a water electrolysis method by which water is able to be efficiently electrolyzed; and a method for producing a catalyst, by which the above-described catalyst is able to be suitably produced.
従来技術、競合技術の概要(英語) BACKGROUND ART
Water electrolyzers have attracted attention as next-generation hydrogen production systems. In water electrolyzers, an oxygen generating anode and a hydrogen generating cathode are essential, and various types of oxygen generating anodes and hydrogen generating cathodes are proposed (, for example, Non-Patent Document 1).
However, conventional oxygen generating anodes have a problem in that oxygen generation over-voltage is high.
