Abstract:
The kinetically slow oxygen evolution reaction (OER) can be inherently boosted by tuning the reconstruction dynamics of active phases. Here, a Cr-modified nickel oxalate pre-catalyst on Ni-Mo foam (NMCrH) is designed to steer the operando surface reconstruction path into OER-active NiOOH with strong Ni-O covalency, more activated lattice oxygen, and a flexible lattice structure. This repurposes the OER route from the adsorbate evolution mode (AEM) to a more efficient lattice oxygen mechanism (LOM), reconciling stability with kinetics, endowing NMCrH with 248 mV at 10 mA cm-2 and 3049 h durability at 1 A cm-2.
