dc.description.abstract | A highly efficient and platinum group metal (PGM)-free oxygen evolution reaction (OER) electrode is developed by immobilizing Ni3N particles on the electrochemically reconstructed amorphous oxy-hydroxides surface, resulting in a twofold higher industrial relevance current density of 1 A cm(geo)(-2) at an ultra-small overpotential eta(O-2) of 271 mV, with a high turnover frequency of 2.53 s(-1), high Faradic efficiency of 99.6 % and exceptional OER stability of 1000 h in continuous electrolysis. Such a unique amorphous-crystalline interface with enriched active sites greatly facilitates electron transport and OER kinetics at the electrode-electrolyte interface. Further, combined with an efficient PGM-free cathode (MoNi4/MoO2@Ni), this electrode demonstrates a current density of 685 mA cm(geo)(-2) at 1.85 V-cell at 70 degrees C in an anion exchange membrane water electrolyzer (AEMWE) operated with ultra-pure water-electrolyte. These findings highlight the design of highly-efficient oxygen-evolving catalysts and significant advancement in the practical implementation of AEMWEs for grid-scale hydrogen production. | - |
