摘      要：Electrochemical nitrogen reduction reaction(NRR)under ambient conditions is highly desirable to achieve sustainable ammonia(NH3)production via an alternative carbon free ***-atom catalysts(SACs)with super high atomic utilization and catalytic efficiency exhibit great potential for ***,a high-performance NRR SAC is facilely prepared via a simple deposition method to anchor Au single atoms onto porousβ-FeOOH *** resulting Au-SA/FeOOH can efficiently drive NRR under ambient conditions,and the NH3 yield reaches as high as 2,860μg·h^(-1)·mg_(Au)^(-1)at-0.4 V *** hydrogen electrode(RHE)with 14.2%faradaic efficiency,much superior to those of all the reported Au-based *** investigations demonstrate that the synergy of much enhanced N_(2)adsorption,directional electron export,and mass transfer ability in Au-SA/FeOOH greatly contributes to the superior NRR *** work highlights a new insight into the design of high efficient NRR electrocatalysts by combination of porous metal oxide matrix and highly active single-atom sites.
