摘要

在这里，通过热活化过氧化氢（H2O2）在接近环境条件（~ 100°C）下证明了硝酸盐（NO3）转化为氨（NH3）高达~ 100 mM和原位级联CO2共还原为尿素（高达~ 1.36 mM）。通过吸附、1H核磁共振（NMR）分析还原产物和15N同位素标记硝酸盐（15NO3）实验，证实了NO3合成NH3。尿素合成的相关结果已通过吸收、1H NMR和高分辨率质谱（HR-MS）分析得到验证。

Near Ambient Condition Ammonia Synthesis and In-Situ CO2 Co-Reduction to Urea from Nitrate

Herein, conversion of nitrate (NO₃^̅) 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 NO₃^̅ has been confirmed using absorption, ¹H nuclear magnetic resonance (NMR) analysis of the reduced product and ¹⁵N isotopic labeled nitratre (¹⁵NO₃^̅) 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.
