Document Type and Number:
WIPO Patent Application WO/2020/250590
Kind Code:
A1
Abstract:
The present invention provides a layered double hydroxide capable of exhibiting higher catalyst activity in an anode reaction of water electrolysis than conventional products. This layered double hydroxide includes a chelating agent and two or more transition metals, and has an average particle size of 100 nm or less.
