摘要:The principle of how the active sites of catalysts match the reaction intermediates has long been sought after. Herein, we report a theory- guided atomic design and fabrication strategy of a C-based catalyst with diatomic Fe-Ni and N, P co- doping for the oxygen evolution reaction ( OER). The configuration matching (with O* on the Ni site and OH* on the adjacent Fe site) and the local electron engineering by P doping significantly facilitate the rate-determining step of OOH* formation. Such diatomic Fe-Ni is demonstrated to be thermodynamically stable and is precisely constructed through the pyrolysis of Fe3+/Ni2+-adsorbed ZIF-8 under NaH2PO2 cofeeding. The synergistic effects endow the catalyst with a low overpotential and high turnover frequency, exceeding all transitionmetal N-based catalysts so far as we know, which provides a deep understanding of the OERmechanism on heteroatomicmetal-based catalysts. This strategy will pave the way for novel catalyst design and the replacement of noble- metal-based catalysts.
