From the electronic structure, the charge state of the Fe site (*O2) can reflect the electrons transfer between Fe and O2, which may have a potential relationship with Fe-N4ORR activity (Supplementary Fig.18). The Bader charge state of Fe and *O2are –1.22 to –1.13eand 0.24 to 0.41e...
Quantum beat measurements on spin-polarized electrons in oxygen ions emerging from magnetized Ni-and Gd layers Employing the time-differential perturbed 纬-angular correlation technique it is shown that 1s- and2s-electrons of highly stripped 16 O(3 )-ions have thei... S Kremeyer,KH Speidel,H...
The energy of atomic orbitals increases as the principal quantum number,n, increases. In any atom with two or more electrons, the repulsion between the electrons makes energies of subshells with different values ofldiffer so that the energy of the orbitals increases within a shell in the ...
Fe3C纳米颗粒(NPs)可以提高多金属M-NC基催化剂的氧还原反应(ORR)的效率;碳纳米管(CNTs)和多孔碳基质在提供更大的接触面积、更多的催化位点以及改善电解质和催化剂之间的界面接触方面具有协同作用。虽然已经有许多NP/CNT复合材料被用于电催化的探索,但由于缺乏有效的制备方法,对Fe3C/CNT材料的研究很少。
electrolytic cell- a cell containing an electrolyte in which an applied voltage causes a reaction to occur that would not occur otherwise (such as the breakdown of water into hydrogen and oxygen) electron gun- the electrode that is the source of electrons in a cathode-ray tube or electron mic...
Electronic-structure analysis revealed that electrons from oxygen removal were localized within vacancies on the defective surface, which directly attacked the C-H bond in propane. The involvement of localized electrons activates the C-H bond via back-donation to the antibonding orbital on the ...
Upon hydrogen introduction, the hydrogen reacts directly with the chemisorbed oxygen, resulting in the formation of water molecules that gradually detach from the material’s surface. The electrons captured by chemisorbed oxygen are then released back into the gas-sensing material. The amount of ...
However, the narrow electrochemical stability window (1.23 V), imposed by hydrogen and oxygen evo-lution, constrains the overall energy density of batteries. The revolutionary ‘‘water-in-salt” electrolytes considerably expand the electrochemical stability window to 3 or even 4 volts, giving rise ...
In all plants, algae and cyanobacteria, sunlight drives the splitting of water molecules into energized electrons and protons, both of which are needed for the reduction of CO2and eventually carbohydrate formation2. Molecular oxygen (O2) is formed during this process, which transformed the Earth’s...
