Boosting urea electrooxidation on oxyanion-engineered nickel sites via inhibited water oxidation
Nature Communications, 2023 Renewable energy-based electrocatalytic oxidation of organic nucleophiles (e.g.methanol, urea, and amine) are more thermodynamically favourable and, economically attractive to replace conventional pure water electrooxidation in electrolyser to produce ...

Ambient Electrosynthesis of Urea with Nitrate and Carbon Dioxide over Iron‐Based Dual‐Sites
Angewandte Chemie, 2022 The development of efficient electrocatalysts to generate key *NH2 and *CO intermediates is crucial for ambient urea electrosynthesis with nitrate (NO3 −) and carbon dioxide (CO2).

Electrocatalytic C–N Coupling for Urea Synthesis
Small Science, 2021 The industrial urea synthesis consists of two consecutive processes, nitrogen + hydrogen → ammonia followed by ammonia + carbon dioxide → urea. The electrocatalytic coupling of carbon source (carbon dioxide) and nitrogen source (nitrogen, nitrite ...

Short-term nitrous oxide emissions from pasture soil as influenced by urea level and soil nitrate [PDF]
, 2004 Nitrogen excreted by cattle during grazing is a significant source of atmospheric nitrous oxide (N2O). The regulation of N2O emissions is not well understood, but may vary with urine composition and soil conditions.
