“…In order to confront this environmental challenge, different scientific and technological approaches have been proposed for the elimination of these nitrogen oxides. For example, the selective catalytic reduction and the capture of NO x − have been explored using different types of solid adsorbent materials, such as zeolites, ,− metal oxides, , activated carbon materials , and metal–organic frameworks (MOFs). , Specifically, nitrogen oxide (NO), a colorless toxic gas, has been captured using ionic liquids and deep eutectic liquids, , as well as several types of metal oxides (CaO, MnO, NiO, SrO, BaO, TiO 2 and SnO 2 , among others) and zeolites, by a selective catalytic reduction …”

The chemisorption of NO on lithium cuprate (Li 2 CuO 2 ) was studied through different techniques, including thermogravimetric and DRIFTS analyses. An initial dynamic thermogravimetric approach depicted similar efficiencies under the absence or presence oxygen (13.5 and 13.8 wt %). However, the NO capture temperature was shifted to higher values in the presence of oxygen. Moreover, the analysis of the outgoing gases showed the evolution of different nitrogen species, explained based on the Li 2 CuO 2 reactivity, solid decompositions, and oxygen content. Then, the isothermal results showed that NO capture was improved with oxygen. Isothermal solid products were characterized, and lithium nitrate and nitrite were identified. Furthermore, a kinetic analysis was performed using two different models, showing that the presence of oxygen significantly modifies the NO sorption process. Moreover, the melting processes of lithium nitrate and nitrite enhanced the whole sorption process in the presence of oxygen; meanwhile, the oxygen absence limits the NO chemisorption.
