DFT Study of Metal (Ag, Au, Pt)-Modified SnS2 for Adsorption of SF6 Decomposition Gases in Gas-Insulated Switchgear.

Langmuir
In this study, the gas-sensitive response of metal (Ag, Au, Pt)-modified SnS2 toward SF6 decomposition gases (SOF2, SO2F2, SO2, H2S) in gas-insulated switchgear was studied by analyzing the adsorption structure, band structure, charge transfer, and ...

Recovery of High-Purity SF6 from Humid SF6/N2 Mixture within a Co(II)-Pyrazolate Framework.

Journal of the American Chemical Society
Sulfur hexafluoride (SF6) is extensively employed in the power industry. However, its emissions significantly contribute to the greenhouse effect. The direct recovery of high purity SF6 from industrial waste gases would benefit its sustainable use, yet ...

Mid-infrared quartz-enhanced photoacoustic sensor for ppb-level CO detection in SF6 gas matrix exploiting a T-grooved quartz tuning fork.

Analytical Chemistry, 2020
An optical sensor for highly sensitive detection of carbon monoxide (CO) in sulfur hexafluoride (SF6) was demonstrated by using quartz-enhanced photoacoustic spectroscopy (QEPAS) technique. A spectrophone composed by a custom 8 kHz T-shaped quartz tuning

Pd-Adsorbed SiN3 Monolayer as a Promising Gas Scavenger for SF6 Partial Discharge Decomposition Components: Insights from the First-Principles Study.

Langmuir
Gas-insulated switchgear (GIS) equipment must be protected by detecting and eliminating the toxic SF6 partial discharge decomposition components. This study employs first-principles calculations to thoroughly investigate the interaction between a Pd ...

Photodetachment of SF6−

Chemical Physics Letters, 1995
Abstract The photodetachment cross section for SF 6 − and the photodetachment threshold for this process have been accurately measured using a newly developed technique. The photodetachment cross section has a threshold at 3.16 eV which is about three times larger than the electron affinity of the SF 6 molecule.

Infrared intensities in crystalline SF6

Spectrochimica Acta, 1962
Abstract Absolute infrared intensities of solid SF 6 have been measured. The results are v 5 , B = 104,000 cm mmole −1 v 6 , B = 12,200 cm mmole −1 The values represent a 1 per cent decrease and 63 per cent increase, respectively, from the gas phase.

Volume electrical discharge in Ne/SF6/C6H14 and pure SF6

Russian Physics Journal, 1999
The electrical and spatial characteristics of a volume electrical discharge are studied as functions of the ratio of partial pressures of the mixture components at varying initial voltage. Early in the discharge, hot (plasma) cathode spots are observed with diffusive plasma flares developing above them.

Partial discharge behavior of protrusion on high voltage conductor in GIS/GIL under high voltage direct current: Comparison of SF6 and SF6 alternative gases

IEEE transactions on dielectrics and electrical insulation, 2020
Recent studies have demonstrated that fluoronitrile (FN) Novec™ 4710 and fluoroketone (FK) Novec™ 5110 show higher dielectric strength than SF6. These gases can be mixed with a buffer gas such as CO2 and technical air to have suitable dielectric ...
