An IrRu alloy nanocactus on Cu_2−xS@IrS_y as a highly efficient bifunctional electrocatalyst toward overall water splitting in acidic electrolytes

Abstract

An IrRu nanocactus on a Cu_2−xS@IrS_y core exhibits excellent electrocatalytic activity and stability toward both the hydrogen evolution reaction and the oxygen evolution reaction in an acidic electrolyte.
