Mo- and Fe-Modified Ni(OH)₂/NiOOH Nanosheets as Highly Active and Stable Electrocatalysts for Oxygen Evolution Reaction

Highly active and stable electrocatalysts for oxygen evolution reaction (OER) are required for industrial hydrogen production. Herein, we report Mo and Fe modification as a synergistic effect to enhance both activity and stability for OER. The Mo- and Fe-modified Ni­(OH)₂/NiOOH nanosheets needs an overpotential of only ∼280 mV to achieve a current density of 100 mA cm^–2 and shows no evidence of degradation after 50 h at such high current density, outperforming all OER catalysts reported to date. This work may provide options for the design and preparation of promising OER electrocatalysts
