Non‐Fermi Liquids as Highly Active Oxygen Evolution Reaction Catalysts
The oxygen evolution reaction (OER) plays a key role in emerging energy conversion technologies such as rechargeable metal‐air batteries, and direct solar water splitting. Herein, a remarkably low overpotential of ≈150 mV at 10 mA cm−2disk in alkaline solutions using one of the non‐Fermi liquids, Hg2Ru2O7, is reported. Hg2Ru2O7 displays a rapid increase in current density and excellent durability as an OER catalyst. This outstanding catalytic performance is realized through the coexistence of localized d‐bands with the metallic state that is unique to non‐Fermi liquids. The findings indicate that non‐Fermi liquids could greatly improve the design of highly active OER catalysts.
