WATER ELECTROLYSIS ELECTRODE CONTAINING CATALYST HAVING THREE-DIMENSIONAL NANOSHEET STRUCTURE, METHOD FOR MANUFACTURING SAME, AND WATER ELECTROLYSIS DEVICE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2021/045302
Kind Code:
A1
Abstract:
The present invention provides: a water electrolysis electrode containing a catalyst having a three-dimensional nanosheet structure with low overvoltage and excellent catalytic activity; a method for manufacturing same, and a water electrolysis device including same. The water electrolysis electrode according to the present invention contains a composite metal oxide, and includes an electrode substrate and a catalyst layer having a three-dimensional nanosheet structure. The water electrolysis electrode manufacturing method according to the present invention comprises a step for immersing an electrode substrate in an electrolytic solution containing a metal oxide precursor, applying a voltage to electrodeposit a composite metal hydroxide, and then performing annealing to form a composite metal oxide. The water electrolysis device according to the present invention includes the water electrolysis electrode according to the present invention as a positive electrode.
