Synergy between multi-components and Ir dopant in Ir-doped high-entropy alloy nanoparticles for efficient and robust ethylene glycol electro-oxidation at an industrial-level current

Ir-doped PdPtAuNiCu HEANs were rationally designed, synthesized, and fabricated in a flow cell fed by ethylene glycol. The cell delivered an industrial-level performance with >300 mA cm −2 under 0.724 V for >1200 hours.
