Oxygen ion supply or removal from the surface is considered to modify equilibria involving electron supply or removal by altering the surface potential of the catalyst and modifying the potential of electrons associated with the surface O/O2− redox couple, hence only long-range electrostatic ...
The A15 β phase of tungsten has recently attracted great interest for spintronic applications due to the finding of giant spin-Hall effect. As β phase is stabilized by oxygen, we have studied the electronic structure of O-doped β-W from first principl
the too strong M–O binding hinders the formation of M-OO2−; while ifeg > 1, the weak interaction lowers the formation rate of O–O bond in M-OOH−[65]. Theegoccupancy model that only takes account of electrons inegorbital...
we conclude the oxygen vacancies are most stable in their fully charge states. The electronic structures and optical properties of β-Ga2O3are calculated by Generalized Gradient Approximation + U formalisms with the Hubbard U parameters set 7.0 eV and 8.5 eV for Ga and O ions, respectivel...
Results indicate that the oxygen vacancy causes a defect level in the energy gap at 1.2 eV above the top of the valence band. To produce oxygen vacancies, amorphous films of Ta2O5 were bombarded with Ar+ ions. XPS results indicate that the Ar-ion bombardment leads to the generation of ...
Chemical looping reforming (CLR) provides a viable process intensification approach for clean and efficient syngas production from carbonaceous fuel with i
SummaryPerovskite electrocatalysts strongly rely on electronic structure regulation, especially for electron configuration (eg) and conductivity. However, current regulation strategies inevitably involve ambiguous entanglement of crystals, electrons, and spin degrees of freedom. Here, we developed a spin-state...
Also, as opposed to pure δ-MnO2, fewer electrons were required for the formation of the chemical bonds with oxygen atoms for Zn over oxygen-deficient δ-MnO2. This suggests that to maximize the attainable power, more valence electrons have been used for the charging and discharging procedures ...
the calculation results showed that the introduction of S vacancies could narrow down the bandgap between the top and bottom valence bans, which indicated the possible enhancement of the electronic conductivity of SnS2(Fig. 10i-k). Consequently, the hierarchical SnS2microspheres electrode has a supe...
