Highly efficient overall water splitting enabled by a bimetallic FeRu-MOF electrocatalyst

Hydrothermally-synthesized FeRu-BDC/NF optimizes electronic structure and conductivity, with low HER (54 mV@10 mA cm −2 ) & OER (230 mV@50 mA cm −2 ) overpotentials, exceptional splitting stability (1.47 V@10 mA cm −2 ).
