Title:
METHOD OF PREPARING NIMO-MOO3-X POROUS NANORODS AND CATHODE CATALYST FOR WATER ELECTROLYSIS COMPRISING PREPARED NIMO-MOO3-X POROUS NANORODS
Document Type and Number:
WIPO Patent Application WO/2024/058606
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a NiMo-MoO3-x porous nanorod catalyst on the basis of a metal-organic framework and a non-precious alloy catalyst prepared thereby. The method for preparing a non-precious alloy catalyst according to the present invention can produce an alloy catalyst retaining excellent HER performance close to that of a commercial platinum catalyst by forming porous nanorods with a wide surface area having a combination of an alloy and an oxide.
