Researchers from Nanjing University have introduced a novel electrocatalyst design strategy based on a unique chemical fermentation (CF) pore-creation mechanism , which enables the fabrication of a multilevel porous carbon architecture embedded with in situ Ni–Fe alloy nanoparticles . This work pioneers a new approach to achieving ultra-efficient oxygen evolution reaction (OER) performance, with a record-low overpotential of 165 mV at 10 mA cm -2 on a non-supported inert electrode and high long-term stability (>90 hours).
