Title:
δ-PHASE TUNGSTEN NITRIDE ELECTRODE MATERIAL, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/029586
Kind Code:
A1
Abstract:
The present disclosure relates to a δ-phase tungsten nitride electrode material, a preparation method therefor, and an application thereof. The δ-phase tungsten nitride electrode material comprises a conductive substrate having an aperture-slit structure and a δ-phase tungsten nitride layer, and at least part of the δ-phase tungsten nitride layer covers the inner wall surface of the aperture-slit structure; the aperture-slit structure comprises an aperture extending inwards on the surface of the conductive substrate and/or a slit extending substantially along the surface of the conductive substrate; and the surface aperture-slit accounts for 5-70%, the opening size of the aperture-slit structure is 500 nm to 500 μm, and the depth of the aperture-slit structure is 1.5 times or more of the opening size. The δ-phase tungsten nitride electrode material of the present disclosure can be used as an acidic or alkaline electrolyte hydrogen production electrode or electrode material, and has excellent hydrogen production performance and stability.
