Further, this Ni-MOF/Ni2[email protected] could be used as cathode in alkaline Zn–H2O cell, reaching a power density of 4.1 mW cm with high stability to integrate hydrogen production with electricity generation. 展开 关键词: MOFs nanoarray Hybridization Interface coupling HER Zn-H2O cell ...
Computational studies19,20,36,42have predicted that hole carriers can be created when C substitutes O sites. By comparing the ionic sizes of Zn2+(0.074 nm), O2−(0.121 nm), and C4+(0.029 nm), as the C ions occupy the O sites, the unit cell volume will contract (compress). Consequ...
It was concluded that s orbital of NH3 (N) and s, p orbitals of Zn atom overlapped at -0.619 Ha. The p orbital of NH3 (N) has interaction with d orbital of Zn atom suggesting the hybridization between them. Based on NH3 removal experimental and XPS spectra results, NH3-ZnFe2O4 ...
The valence bands near Fermi level are mainly contributed by O 2p states, next by Zn 3d states, leading to a significant hybridization of O 2p and Zn 3d levels, while the lowest unoccupied state is mainly dom- inated by Zn nanotubes68. 4 s sates. The features of the DOSs of the ...
