Abstract
Herein, conversion of nitrate (NO3̅) to ammonia (NH3) up to ∼100 mM and in-situ cascade CO2 co-reduction to urea (up to ∼1.36 mM) has been demonstrated by thermally activated hydrogen peroxide (H2O2) at near ambient conditions (∼100 °C). NH3 synthesis from NO3̅ has been confirmed using absorption, 1H nuclear magnetic resonance (NMR) analysis of the reduced product and 15N isotopic labeled nitratre (15NO3̅) experiement. The results associated with the urea synthesis have been verified using absorption, 1H NMR, and high resolution-mass spectrometry (HR-MS) analysis.
期刊介绍：
The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
