US 2024/0200211 A1 · ELECTRODE CATALYST COMPOSITE CONTAINING 2D TRANSITION METAL CHALCOGENIDE MATERIAL FOR WATER ELECTROLYSIS AND MANUFACTURING METHOD THEREOF

Abstract

An embodiment of the present invention provides an electrocatalyst composite including a 2D transition metal chalcogenide material for water electrolysis and a method for manufacturing the same. According to one embodiment of the present invention, the electrocatalyst composite for water electrolysis is manufactured by hetero-junctioning 2D nickel cobalt sulfide (NiCo2S4) and 2D rhenium sulfide (ReS2) to allow for high activity and application over a broad pH range during water electrolysis.
