Breaking the linear correlations for enhanced electrochemical nitrogen reduction by carbon-encapsulated mixed-valence Fe7(PO4)6
文献摘要：
Electrochemical nitrogen reduction(NRR)is deemed as a consummate answer for the traditional Haber-Bosch technology.Breaking the linear correlations between adsorption and transition-state energies of intermediates is vital to improve the kinetics of ammonia synthesis and obtain a less energy-intensive process.Herein,carbon-encapsulated mixed-valence Fe7(PO4)6 was prepared and applied as an electro-catalyst for high-efficiency NRR.A dramatic faradaic efficiency(FE)of 36.93％and an NH3 production rate of 13.1 μg h-1 mg-1cat were obtained at-0.3 V versus RHE,superior to nearly all Fe-based catalysts.Experiments and DFT calculations revealed that the superior performance was ascribed to the synergistic effect of mixed-valence iron pair,which braked the linear correlations to improve the kinetics of ammo-nia from collaborative hydrogenation and*NH3 separation.This work proves the feasibility of mixed-valence catalysts for nitrogen reduction and thus opening a new avenue towards artificial nitrogen-fixation catalysts.
