Title:
ELECTROCATALYTIC WATER OXIDATION HOMOGENEOUS DIATOMIC CATALYST, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/093285
Kind Code:
A1
Abstract:
The present invention relates to the technical fields of electrocatalysis and chemical industry, and specifically relates to an electrocatalytic water oxidation homogeneous diatomic catalyst, and a preparation method therefor and a use thereof. The catalyst comprises a carrier and a homogeneous diatomic active site having an adjacency structure, and the active site is anchored in the carrier; the carrier is one or more than two of an oxide, a hydroxide, and an oxyhydroxide of a 3d transition metal; a coordination structure is formed between the two atoms and the carrier. The intrinsic activity of a diatomic dispersed catalytic material prepared by the method in an electrocatalytic water oxidation reaction is equivalent to that of the existing natural photosynthetic system II having the highest efficiency, the water oxidation initial potential is merely 170 mV, and the stability is kept for 650 hours under a current density of 20 mA cm-2-; and the preparation method is simple and has low cost.
