Abstract
Abstract The renewable‐energy‐powered electroreduction of nitrate (NO 3 − ) to ammonia (NH 3 ) has garnered significant interest as an eco‐friendly and promising substitute for the Haber–Bosch process. However, the sluggish kinetics hinders its application at a large scale. Herein, we first calculated the N‐containing species (*NO 3 and *NO 2 ) binding energy and the free energy of the hydrogen evolution reaction over Cu with different metal dopants, and it was shown that Zn was a promising candidate. Based on the theoretical study, we designed and synthesized Zn‐doped Cu nanosheets, and the as‐prepared catalysts demonstrated excellent performance in NO 3 − ‐to‐NH 3 . The maximum Faradaic efficiency (FE) of NH…
