Abstract
Urea electrosynthesis from carbon dioxide and nitrates powered by green electricity is a zero‐carbon route for urea production. Simultaneously achieving high activity and long‐term stability is a prerequisite for the industrialization of urea electrosynthesis. In this study, we propose an electron bridge strategy based on a Pd1 and Ni1 dual single‐atom alloy to boost the electrocatalytic activity and durability for urea electrosynthesis. The single‐atom Ni1 sites act as electron bridges to promote charge transfer from Cu to Pd1 sites, leading to charge‐polarized Pd–Cu sites, which upshift the d‐band center and improve oxidation resistance of the catalyst. Consequently, the Pd1 and Ni1 dual single‐atom sites simultaneously accelerates both carbon dioxide reduction and nitrates reduction half‐reactions, while facilitating the first C–N coupling step. The Pd1 and Ni1 dual single‐atom alloys deliver a urea yield rate of 541.6 mmol gcat −1 h−1 with a urea Faradaic efficiency of 57.3%. Remarkably, this catalyst achieves a record durability of 1700 h at a current density of 40 mA cm−2. This work provides new insights into the synergistic catalysis of complex multi‐molecule reactions through cooperative multiple active sites.
