The reactions of lithium oxide, sodium peroxide, the nitrites of sodium and potassium, and the nitrates of lithium, sodium and potassium with molten potassium pyrosulfate were investigated. It was found that gaseous products of reactions of peroxide, nitrites and nitrates consisted of, respectively, oxygen, nitrogen dioxide plus nitric oxide, and nitrogen dioxide plus oxygen. Pyrosulfate, after accepting an oxide ion from each of the above oxyanions, was converted into sulfate. The range of temperatures and stoichiometries of these reactions have been established.

The reactions of hydroxides of lithium, sodium and potassium; hydrogen carbonates of sodium and potassium and carbonates of lithium, sodium and potassium with molten potassium pyrosulfate were studied. It was found that during these Lux-Flood acid-base reactions, hydroxides, hydrogen carbonates and carbonates reacted with pyrosulfate to produce water, water plus carbon dioxide and carbon dioxide alone respectively, as the gaseous products. Pyrosulfate, after accepting oxide ions from these bases, was found in each case to be converted into sulfate. The temperatures and stoichiometries of these reactions have been established.

AbstractBlack phosphorus nanostructures have recently sparked substantial research interest for the rational development of novel chemosensors and nanodevices. For the first time, the influence of alkali metal doping of black phosphorus monolayer (BP) on its capabilities for nitrogen dioxide (NO2) capture and monitoring is discussed. Four different nanostructures including BP, Li-BP, Na-BP, and K-BP were evaluated; it was found that the adsorption configuration on Li-BP was different from others such that the NO2 molecule preferred a vertical stabilization rather than a parallel configuration with respect to the surface. The efficiency for the detection increased in the sequence of Na-BP < BP < K-BP < Li-BP, with the most significant improvement of + 95.2% in the case of Li doping. The Na-BP demonstrated the most compelling capacity (54 times higher than BP) for NO2 capture and catalysis (− 24.36 kcal/mol at HSE06/TZVP). Furthermore, the K-doped device was appropriate for both nitrogen dioxide adsorption and sensing while also providing the highest work function sensitivity (55.4%), which was much higher than that of BP (10.4%).
