Title:
CATALYST, ELECTRODE, WATER ELECTROLYSIS METHOD, AND METHOD FOR PRODUCING CATALYST
Document Type and Number:
WIPO Patent Application WO/2020/230530
Kind Code:
A1
Abstract:
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.
