Jun 15, 2020 · Here we directly coupled N2 and CO2 in H2O to produce urea under ambient conditions. The process was carried out using an electrocatalyst consisting of PdCu alloy nanoparticles on TiO2...

Feb 1, 2019 · Hydrate dissociation equilibrium conditions for the mixture of carbon dioxide (CO2), nitrogen (N 2), and water (H 2O) are measured in the temperature range of 274.15–280.15 K.

Nov 15, 2023 · Water (H 2 O) microdroplets are sprayed onto a graphite mesh covered with a CuBi 2 O 4 coating using a 1:1 mixture of N 2 and CO 2 as the nebulizing gas. The resulting microdroplets contain urea [CO (NH 2) 2] as detected by both mass spectrometry and 13 C nuclear magnetic resonance.

Here we directly coupled N2 and CO2 in H2O to produce urea under ambient conditions. The process was carried out using an electrocatalyst consisting of PdCu alloy nanoparticles on TiO2...

Jan 18, 2023 · One-pot synthesis of urea [(NH2)2CO] from easily available small molecules, that is, N2, CO2, and H2O, is an extremely attractive but very challenging reaction. 2D-CdS@3D-BiOBr composites with S-sc...

Sep 13, 2024 · Direct synthesis of urea from CO 2, N 2, and H 2 O through photocatalysis stands out as an effective solution to mitigate the over-release of CO 2 and alleviate the high costs associated with nitrogen fertilizer production. The 20% CdS@Bi 2 WO 6 sample exhibits optimal activity under visible light, achieving a urea yield of 10.0 μmol·g –1 ·h –1.

Here we directly coupled N 2 and CO 2 in H 2 O to produce urea under ambient conditions. The process was carried out using an electrocatalyst consisting of PdCu alloy nanoparticles on TiO 2 nanosheets. This coupling reaction occurs through the formation of C-N bonds via the thermodynamically spontaneous reaction between *N=N* and CO.

Aug 1, 2022 · Zeolite 3A shows a good adsorption selectivity for CO 2 /H 2 O and N 2 /H 2 O. The thermal wave peak time of N 2 /H 2 O is 0.71–8.31 min longer than that of CO 2 /H 2 O, while the peak temperature of N 2 /H 2 O is 2–16 °C smaller than that of CO 2 /H 2 O.

May 26, 2022 · Understanding the phase behaviour of (CO2 + water + permanent gas) systems is critical for implementing carbon capture and storage (CCS) processes, a key technology in reducing CO2 emissions. In this paper, phase behaviour data for (H2O + N2) and (CO2 + H2O + N2) systems are reported at temperatures from 323 to 473 K and pressures up to 20 MPa.

Feb 25, 2021 · Electrocatalytic C−N bond coupling to convert CO 2 and N 2 molecules into urea under ambient conditions is a promising alternative to harsh industrial processes. However, the adsorption and activation of inert gas molecules and then the driving of the C–N coupling reaction is energetically challenging.
