Great efforts have been made on the development of new strategies for the synthesis of single-atom catalysts. In the design of SACs, substrates are materials that host the single atoms, providing a stable and accessible surface for catalytic reactions. The interaction between the single metal atoms and the substrate (carrier or support) is critical as it determines the stability and activity of the catalyst. Unraveling the substrate adsorption structure–performance relationship is pivotal for supported metal single-atom catalysts. On the other hand, the catalytic performance largely depends on the interaction among single atoms. In this review, we summarize in SACs-based electrochemical synthesis of ammonia. The reaction mechanism of these single-atom catalysts and their applications are discussed and assessed.

Water serves as the primary proton donor (in aqueous electrolytes) in the absence of hydronium, which can influence the competition between CO<sub>2</sub>RR and the hydrogen evolution reaction (HER). Despite studies dating back to the 1980s demonstrating that electrolyte composition significantly impacts CO<sub>2</sub>RR performance, the effects of the electrolyte composition on the interfacial water properties have remained largely unexplored.
