Synthesis of High‐Entropy‐Alloy Nanoparticles by a Step‐Alloying Strategy as a Superior Multifunctional Electrocatalyst

in 1 m KOH + 1 m MeOH and a half-wave potential of 0.86 V (vs RHE.) in 0.1 m KOH. The work further expands the spectrum of possible metal alloys, which is important for the broad compositional space and future data-driven material discovery.
