▎ 摘  要

NOVELTY - Water splitting catalyst comprises porous carbon layer, bimetallic metal alloy core dispersed on the porous carbon layer, and a single-atom precious metal dispersed on the bimetallic metal alloy core. The oxygen is adsorbed on a surface of the bimetallic metal alloy core. USE - Water splitting catalyst for use in water splitting system, and oxygen evolution reaction or hydrogen evolution reaction (all claimed). ADVANTAGE - The water splitting catalyst has improved water splitting reaction rate by increasing conductivity of the porous carbon layer, and increased mobility of electrons. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a method for preparing a water splitting catalyst, which involves:(a) forming a mixed solution comprising a metal-polymer micelle (M1M2-micelle) by mixing a first metal precursor, a second metal precursor, and a polymer solution; (b) forming an intermediate in which a precious metal is arranged on a surface of the metal-polymer micelle by injecting a precious metal precursor into the mixed solution; and (c) heat-treating the intermediate; and 2. a water splitting system, which comprises: water splitting catalyst.
