Ammonia plays an indispensable role in global agroeconomics, chemical industries, energy carriers, and other diverse applications. To meet the demand for ammonia in these roles, the artificial synthesis of ammonia has traditionally relied on the well-established Haber–Bosch process that is commercially viable but energy intensive. Recently, the drive for sustainable alternatives has fueled interest in the development of electrochemical nitrogen reduction (eNRR) as a pathway for carbon-free ammonia synthesis. Nevertheless, research in the eNRR field remains elusive, partly because of the ominous presence of reactive nitrogen-containing species (Nr) and the lack of a thorough understanding of eNRR mechanistics. Herein, we provide an overview of efforts highlighting measures to avoid false positives and advancing mechanistic understanding of the eNRR process.
