Abstract

Ambient urea synthesis via C-N coupling from CO₂ and nitrate reduction offers an attractive alternative to the Bosch-Meiser route, but it is hindered by the lack of efficient catalysts. Herein, we report that Fe-doped InOOH nanosheets effectively catalyze the coreduction of CO₂ and nitrate, giving a high Faradaic Efficiency of 26.9%, a yield rate of 980.6 μg h^-1 mg_cat.^-1, and a good durability. Theoretical calculations further elucidate that iron dopants can tailor the reactivity of the In site, facilitating the hydrogenation of the key *CO₂NH₂ intermediate and suppressing the hydrogen production with a higher energy barrier.
