Electrocatalytic Urea Synthesis via C─N Coupling Over Fe‐Based Catalyst

Abstract

Abstract Electrochemical urea synthesis under ambient conditions offers a promising alternative to traditional methods, yet suffers from inefficient production due to poor binding of reactants to the catalyst surface, leading to competitive pathways. In this study, we report an electrochemical route for urea synthesis by dual reduction of CO 2 and N 2 gases using iron phthalocyanine (FePc) catalyst. The FePc electrocatalyst showed a urea yield rate of 357 µmol h −1 g cat −1 with a Faradaic efficiency (FE) of 14.36% at −0.4 V versus RHE. This work offers an awareness into the development of an electrochemical route for the efficient electrosynthesis of urea via C─N coupling.
