HYDROLYSIS PHOTOCATALYST, ELECTRODE, AND HYDROLYSIS APPARATUS

Title:

HYDROLYSIS PHOTOCATALYST, ELECTRODE, AND HYDROLYSIS APPARATUS

Document Type and Number:

WIPO Patent Application WO/2019/181392

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing: a hydrolysis photocatalyst which has excellent durability and visible-light response, and which can form a hydrolysis apparatus capable of producing a large amount of gas; and a hydrolysis apparatus having the hydrolysis photocatalyst. This hydrolysis photocatalyst contains a compound represented by formula (Ln)2CuO4 and is used in an electrode which generates gas by being irradiated with light while immersed in water. In the formula, Ln represents a lanthanoid, and may be partially substituted with elements of Group 2 to Group 4 of the Periodic Table.
