Boosting Electrochemical Urea Synthesis via Constructing Ordered Pd-Zn Active Pair.

ABSTRACT: Electrochemical co-reduction of nitrate (NO₃^-) and carbon dioxide (CO₂) has been widely regarded as a promising route to produce urea under ambient conditions, however the yield rate of urea has remained limited. Here, we report an atomically ordered intermetallic pallium-zinc (PdZn) electrocatalyst comprising a high density of PdZn pairs for boosting urea electrosynthesis. It is found that Pd and Zn are responsible for the adsorption and activation of NO₃^- and CO₂, respectively, and thus the co-adsorption and co-activation NO₃^- and CO₂ are achieved in ordered PdZn pairs. More importantly, the ordered and well-defined PdZn pairs provide a dual-site geometric structure conducive to the key C-N
