Generally, there are three bonding configurations that appear in the NG lattice. As described by Wang et al.17: (1) a graphitic N atom is an N atom that replaces a C atom in the graphene lattice and bonds with three other adjacent C atoms in the hexagonal ring; (2) a pyridinic N ...
At low energy (2eV/molecule) with 17% hydrogen, ethane was the most abundant product but with a much lower selectivity (45%) than without hydrogen (∼80%). Conversely, ethylene (15%) and acetylene (25%) selectivities were three times higher than in the absence of hydrogen. The ...
This study reveals that various types of carbon–nitrogen bonds of the support affect activity and selectivity of hydrogenation of cinnamaldehyde to hydrocinnamaldehyde reaction differently by palladium active phase. The catalyst supports were synthesized with thermal treatment at three different heat ...
three possible reaction pathways for this deprotonation step, including the transfer of proton to: (I) carboxyl O4 of Asp63 (Supplementary Fig.19), (II) carboxyl O3 of a substrate without bridging waters (Supplementary Fig.20), and (III) carboxyl O3 of the substrate with the help of ...
The blast of ions splits the nitrogen-three molecules from the sodium and, in the excited state, the nitrogen molecules can bond with each other. Not surprisingly, the reaction produces a good bit of heat, so putting the brakes on it requires an incredible blast of cold — the one ...
Engineering of defects in semiconductors provides an effective protocol for improving photocatalytic N2 conversion efficiency. This review focuses on the s
These three cases represent graphitic-N, pyridinic-N, and pyrrolic-N atoms in the N-doped Gr, respectively. (b) Calculated binding energies of various cases of one Ga atom adsorption on the N-doped monolayer Gr surface and on the surface of Gr with C–O bonds. (c) Top-view and side...
Although some p-block element compounds could also react with CO 24–38 or isonitriles28,39,40, the strongest s-bond among the three bonds in a triple bond remained intact in all cases. On the other hand, chemistry containing Lewis-base adduct of sp2–sp3 diborane(4) compounds has been...
The latter species is so common that it is easy to forget its uniqueness as the archetype of species with three-center/two-electron bonds, of electron-deficient as opposed to electron-precise species, of boron compounds, and the general cluster and cage chemistry that arises from these ...
All azidonitramino ethers are liquid with excellent energetic performance and are promising candidates for new environmentally friendly energetic materials.
