Spin polarization strategy to deploy proton resource over atomic-level metal sites for highly selective CO2 electrolysis
文献摘要：
Unlocking of the extremely inert C=O bond during electrochemical CO2 reduction demands subtle regulation on a key"resource",protons,necessary for intermediate conversion but also readily trapped in water splitting,which is still challenging for developing efficient single-atom catalysts limited by their structural simplicity usually incompetent to handle this task.Incorporation of extra functional units should be viable.Herein,a proton deployment strategy is demonstrated via"atomic and nanostructured iron(A/N-Fe)pairs",comprising atomically dispersed iron active centers spin-polarized by nanostructured iron carbide ferromagnets,to boost the critical protonation steps.The as-designed catalyst displays a broad window(300 mV)for CO selectivity＞90％(98％maximum),even outperforming numerous cutting-edge M-N-C systems.The well-placed control of proton dynamics by A/N-Fe can promote*COOH/*CO formation and simultaneously suppress H2 evolution,benefiting from the magnetic-proximity-induced exchange splitting(spin polarization)that properly adjusts energy levels of the Fe sites'd-shells,and further those of the adsorbed intermediates'antibonding molecular orbitals.
