Title:
IN SITU-GROWN POROUS-TIO2-X-BASED CATALYST AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/169061
Kind Code:
A1
Abstract:
The present invention relates to an oxygen evolution reaction (OER) catalyst having a highly electrically-conductive titanium (II) oxide applied as a support, thereby having excellent OER catalytic performance and durability and, specifically, to a porous OER catalyst and a preparation method therefor, the catalyst comprising a porous titanium oxide support satisfying TiO2-x (0.1≤ x < 2), and a metal hydroxide supported on the titanium oxide support.
