CoFe‐LDH with broad interlayer space is strongly coupled with 2D graphene, leading to a novel composite with well interconnected conductive networks and enhanced mass and charge transfer ability. As reported by Jieshan Qiu, Chang Yu and co‐workers in article number 1500782, this hydride material can deliver a low overpotential of 325 mV at 10 mA cm −2 , indicative of the superiority and potential as cost‐effective and highly active catalysts for efficient oxygen evolution.
