“…[6b,9] Moreover, Liu et al proposed the adjacent *NH species or dimerized *N 2 can bond with CO molecular, resulting a superior activity for urea synthesis. [10] In this regard, the design of efficient catalysts for urea electrosynthesis is expected to be bi-functional in both CO 2 RR and NO 3 À RR. [11] However, in aqueous electrolytes, owing to the low solubility of CO 2 and the higher polarity of water molecule than CO 2 , surface sites are preferentially occupied by water, therefore, hydrogen evolution reduction (HER) is generally more preferred than CO 2 reduction, the number of catalysts capable of preferential CO 2 RR over hydrogen production (HER) is limited.…”

Electrochemical reduction of CO2 and nitrate offers a promising avenue to produce valuable chemicals through the using of greenhouse gas and nitrogen‐containing wastewater. However, the generally proposed reaction pathway of concurrent CO2 and nitrate reduction for urea synthesis requires the catalysts to be both efficient in both CO2 and nitrate reduction, thus narrowing the selection range of suitable catalysts. Herein, we demonstrate a distinct mechanism in urea synthesis, a tandem NO3‐ and CO2 reduction, in which the surface amino species generated by nitrate reduction play the role to capture free CO2 and subsequent initiate its activation. When using the TiO2 electrocatalyst derived from MIL‐125‐NH2, it intrinsically exhibits low activity in aqueous CO2 reduction, however, in the presence of both nitrate and CO2, this catalyst achieves an excellent urea yield rate of 43.37 mmol･g‐1･h‐1 and a Faradaic efficiency of 48.88% at ‐0.9 V vs. RHE in a flow cell. Even at a low CO2 level of 15%, the Faradaic efficiency of urea synthesis remains robust at 42.33%. The tandem reduction procedure was further confirmed by in‐situ spectroscopies and theoretical calculations. This research provides new insights into the selection and design of electrocatalysts for urea synthesis.
