Ammonia Electrosynthesis with High Selectivity under Ambient Conditions via a Li<sup>+</sup> Incorporation Strategy
We report the discovery of a dramatically
enhanced N<sub>2</sub> electroreduction reaction (NRR) selectivity
under ambient conditions
via the Li<sup>+</sup> incorporation into poly(<i>N</i>-ethyl-benzene-1,2,4,5-tetracarboxylic
diimide) (PEBCD) as a catalyst. The detailed electrochemical evaluation
and density functional theory calculations showed that Li<sup>+</sup> association with the O atoms in the PEBCD matrix can retard the
HER process and can facilitate the adsorption of N<sub>2</sub> to
afford a high potential scope for the NRR process to proceed in the
“[OLi<sup>+</sup>]·N<sub>2</sub>H<sub><i>x</i></sub>” alternating hydrogenation mode.
This atomic-scale incorporation strategy provides new insight into
the rational design of NRR catalysts with higher selectivity
