The rough surface could induce rugged N–doped graphene film that easily absorbed more pentachloropyridine molecule, leading to higher nitrogen content in graphene (shown in XPS characterization, e.g. 8.2 at % a
The oxidation state of nitrogen in nitrogen dioxide is +4. The molecule has an unpaired electron. Both these factors contribute to its reactivity. Nitrogen dioxide readily converts to other forms of nitrogen oxides. It coexists in equilibrium with its dimeric form, N2O4. The latter is more sta...
However, the N2 molecule is stable and inert with a strong triple bond and low polarizability.1, 2 The Haber-Bosch process that was developed 100 years ago is still employed in industry for NH3 synthesis at high temperatures (>300°C) and pressures (>10 MPa).3 This energy- and capital-...
Sun et al. discovered through theoretical calculations that the Mo ion at the edge has an atomic charge of + 0.963 |e|, and the positively charged Mo edge has a vital role in polarizing and activating the N2 molecule (Fig. 3a). As indicated in the free energy curve (Fig. 3b), the ...
Excited (Acr+-Mes*) catalyst formed upon blue LEDs irradiation allows for the single electron oxidation process of aziridine 160 alongside with the reduced photocatalyst (Acr•-Mes) formation. The radical cation 163 is then converted into the nitrone radical 164 through the r...
In this case, the unpaired electron occupies a level which is reminiscent of a πMO in the NO gas-phase molecule. A feature common to both substitutional and interstitial nitrogen is that the unpaired elec- tron is rather localized, as proved by the calculation of the hyperfine coupling ...
What is a polar covalent molecule? Where is the lowest electronegativity found on the periodic table? Explain why nitrogen has a higher polarizability than fluorine. What is the oxidation state of nitrogen in Mg(NO2)2? What is the electron configuration for nitrogen? What is the electronegativity...
However, together with the dipole moment, several other factors should also be taken into account, such as the charge transfer ability, adsorption energy, and the LUMO (lowest unoccupied molecule orbit) energy values for different gas molecules that accounts for the s electivity36. ssyccnmTt...
After producing and releasing NH3 from a distance, nitrogen atoms bound to the catalyst surface start forming the second NH3 molecule along a comparable pathway. In the alternate pathway, protons are continually introduced to two nitrogen atoms, resulting in the successive formation of two NH3 ...
In a typical p-PSC structure, the perovskite layer is stacked between planar thin films of the electron transport layer (ETL) and the hole transport layer (HTL) [19,20]. Various strategies have been utilized to increase the photovoltaic properties of planar PSCs, including high-quality perovski...
