Developing highly efficient catalysts for oxygen evolution reactions (OER) is a key step for rechargeable metal–oxygen batteries and water splitting. Usually, binary NiFe or ternary NiCoFe nano-alloys are used as the OER catalysts. Herein, combining the precursor alloy design with chemical etching,...
