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 ...
as gas sensors, first-principles calculations are carried out to explore the stability and electronic properties of Zn12O12 cluster- assembled nanowires and the adsorption behaviors of environmental gases on the Zn12O12-based nanowires, including CO, NO, NO2, SO2, NH3, CH4, CO2, O2 and H2....
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...
2.3. Synthesis of 1D ZnFe2O4@SiO2 (ZS) nanochains 0.10 g ZnFe2O4 nanoparticles, TEOS and NH3·H2O were added into a mixed solution containing anhydrous ethanol and water under ultrasonic stirring. Then, a cuboid cymbal magnet was placed next to the beaker for 6 h [38]. Finally, the ...
However, inert products such as ZnCl2·2NH3 will be formed to decrease the energy density of the battery [76]. The possible chlorine evolution and the poison of the catalyst cannot be ignored due to the presence of Cl− ions, which have a negative significance on the O2 electrocatalysis ...
