Enhanced Electrocatalytic Urea Synthesis over Iron-Doped InOOH Nanosheets under Ambient Conditions

Ambient urea synthesis via C-N coupling from CO<sub>2</sub> 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 CO<sub>2</sub> and nitrate, giving a high Faradaic Efficiency of 26.9%, a yield rate of 980.6 μg h<sup>-1</sup> mg<sub>cat.</sub><sup>-1</sup>, 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 *CO<sub>2</sub>NH<sub>2</sub> intermediate and suppressing the hydrogen production with a higher energy barrier.

Abstract

Ambient urea synthesis via C-N coupling from CO<sub>2</sub> 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 CO<sub>2</sub> and nitrate, giving a high Faradaic Efficiency of 26.9%, a yield rate of 980.6 μg h<sup>-1</sup> mg<sub>cat.</sub><sup>-1</sup>, 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 *CO<sub>2</sub>NH<sub>2</sub> intermediate and suppressing the hydrogen production with a higher energy barrier.
