In mechanistic investigations, we propose that the oxidative coupling of CO and NH3 on Pt leads to cyanate formation, followed by the Wöhler reaction to form urea. This approach offers a practical route for urea production with high electron efficiency by enabling Pt-catalysed reactions between ...
In solution, this complex reacts with H2 at ambient temperature (22 °C) and low pressure (1 or 4 bar) to form NH3. In the solid state, it is converted into the tri(iron)bis(imido) species, [(Cp′Fe)3(μ3-NH)2], by addition of H2 (10 bar) through an unusual solid...
Atmospheric NH3readily condenses onto sulfuric acid and with nitric acid to form what is often a ternary mixture of sulfate (\(\text {SO}_{4}^{2-}\)), ammonium (\(\text {NH}_{4}^{+}\)), and nitrate (\(\text {NO}_{3}^{-}\)) in water, which commonly contains salts such...

We demonstrated full Iodine content, which might be related to the enhanced stability, in a more compact PbI6 framework with reduced unit-cell volume. A structural investigation from neutron powder diffraction (NPD) data of an undeuterated specimen was essential to determine the configuration of...
At the reaction conditions applied, AgNCO does not form an ionic diammine species (e.g. [Ag(NH3)2]+) as known from related silver salts. In this sense, the solvation chemistry of AgNCO exhibits a rarely observed feature.doi:10.1002/zaac.202000210...
Full feed condition: rich (0.97 ≤λ < 1.00), stoichiometric (λ = 1.00) and lean condition (1.00 < λ≤ 1.03) with 0.01 intervals of λ, GHSV = 150,000 h−1. In addition to NO, CO and HCs conversion, NH3 and N2O during a course of NO reduction were examined with respect to ...
