Web20 de dic. de 2024 · This result confirmed that water vapor cannot compete with NO 2 and decrease the NO 2 removal performance of Al-PMOF, which was attributed to the robust nature of Al-PMOF. The improved NO 2 adsorption capacity at wet conditions was probably caused by the water vapor film on Al-PMOF that enhanced the adsorption and reaction … NO 2 is paramagnetic due to its unpaired electron, while N 2 O 4 is diamagnetic. At 150 °C, NO 2 decomposes with release of oxygen via an endothermic process (ΔH = 14 kJ/mol): NO 2 → NO + 1 ⁄ 2 O 2 As an oxidizer. As suggested by the weakness of the N–O bond, NO 2 is a good oxidizer. Ver más Nitrogen dioxide is a chemical compound with the formula NO 2. It is one of several nitrogen oxides.
