Developing efficient bifunctional electrocatalysts for overall water splitting in acidic conditions is the essential step for proton exchange membrane water electrolyzers (PEMWEs). We first report the synthesis of core–shell structure nanoparticles (NPs) with an Au core and an AuIr2 alloy shell (Au@...
