Shaped Ir-Ni bimetallic nanoparticles for minimizing Ir utilization in oxygen evolution reaction

Shaped Ir-Ni bimetallic nanoparticles were synthesized and used for electrocatalytic oxygen evolution reaction (OER). The obtained bimetallic nanoparticles showed significantly enhanced Ir mass activity and durability compared with Ir nanoparticles.
