Abstract
Conjointly activating metal and oxygen sites to trigger the adsorbate evolution and lattice oxygen mechanisms coupled path holds promise for balancing activity and stability in oxygen evolution reaction catalysts, yet confronting great challenges. Herein, we develop Fe species and oxygen vacancies co-regulated Ni-(oxy)hydroxide from the deep reconstruction of Fe-Ni2P/NiMoO4 pre-catalyst achieving the adsorbate evolution and lattice oxygen dual-path mechanism. Experimental details and theoretical calculation analysis reveal the enhanced adsorbate evolution mechanism kinetics at the Ni sites via the co-regulation of Fe species and oxygen vacancies, while the Fe incorporation activates the O sites with preferable…
