Near Ambient Condition Ammonia Synthesis and In-Situ CO<sub>2</sub> Co-Reduction to Urea from Nitrate
Herein, conversion of nitrate (NO<sub>3</sub><sup>̅</sup>) to ammonia (NH<sub>3</sub>) up to ∼100 mM and in-situ cascade CO<sub>2</sub> co-reduction to urea (up to ∼1.36 mM) has been demonstrated by thermally activated hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) at near ambient conditions (∼100 °C). NH<sub>3</sub> synthesis from NO<sub>3</sub><sup>̅</sup> has been confirmed using absorption, <sup>1</sup>H nuclear magnetic resonance (NMR) analysis of the reduced product and <sup>15</sup>N isotopic labeled nitratre (<sup>15</sup>NO<sub>3</sub><sup>̅</sup>) experiement. The results associated with the urea synthesis have been verified using absorption, <sup>1</sup>H NMR, and high resolution-mass spectrometry (HR-MS) analysis.
