Herein, a remarkably low overpotential of ≈150 mV at 10 mA cm−2 disk 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. © 2017 The Authors. Published by WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim |
