Uniform yolk-shell iron sulfide-carbon nanospheres for superior sodium-iron sulfide batteries.
Sodium-metal sulfide battery holds great promise for sustainable and cost-effective applications. Nevertheless, achieving high capacity and cycling stability remains a great challenge. Here, uniform yolk-shell iron sulfide-carbon nanospheres have been synthesized as cathode materials for the emerging sodium sulfide battery to achieve remarkable capacity of ∼ 545 mA h g(-1) over 100 cycles at 0....
متن کاملEffect of sodium sulfide on Ni-containing carbon monoxide dehydrogenases.
The structure of the active-site C-cluster in CO dehydrogenase from Carboxydothermus hydrogenoformans includes a mu(2)-sulfide ion bridged to the Ni and unique Fe, whereas the same cluster in enzymes from Rhodospirillum rubrum (CODH(Rr)) and Moorella thermoacetica (CODH(Mt)) lack this ion. This difference was investigated by exploring the effects of sodium sulfide on activity and spectral prope...
متن کاملThe assistance of microwave process in sludge stabilization with sodium sulfide and sodium phosphate.
After industrial wastewater sludge passed through an acid-extraction process to reclaim most of the copper ions in it, the residue may still need to be treated by stabilization technologies. The common method for the stabilization of hazardous waste in Taiwan is by cement solidification. However, this method has the disadvantage of an increase in waste volume. In this study, it was tried to com...
متن کاملCatalytic Determination of Traces of Tellurium (IV) Using the Reduction of Lauth’s Violet with Sodium Sulfide
A simple, rapid and sensitive method has been developed for determination of traces of tellurium (IV) (7.0-120.0 ng/ml) based on it’s catalytic effect on the reduction reaction of lauth’s violet by sulfide ion at pH 4.2. The reaction is monitored spectrophotometrically by measuring the decrease in absorbance of lauth’s viole at 600 nm by the fixed time method. The detection limit is 5.0 ng/ml a...
متن کاملRapid synthesis of small silver nanocubes by mediating polyol reduction with a trace amount of sodium sulfide or sodium hydrosulfide.
This paper describes the fastest route to monodispersed silver nanocubes. By adding a trace amount of sodium sulfide (Na(2)S) or sodium hydrosulfide (NaHS) to the conventional polyol synthesis, the reaction time was significantly shortened from 16-26 hours to 3-8 minutes. By merely adjusting the reaction time, monodispersed silver nanocubes of 25-45 nm in edge length were rapidly and routinely ...
