On the Structure of Graphite Fluoride

Zeitschrift für anorganische und allgemeine Chemie, 1987
AbstractThe structure of graphite fluoride, (C2F)n has been investigated by X‐ray analyses, solid state 19F‐n.m.r., and electron microscopy for well characterized and crystallized samples obtained from natural graphite or HOPG (highly oriented pyrolytic graphite). On the basis of the present results and structural properties derived from previous works,

Electronic structure of graphite fluorides

Physics Letters A, 2001
Abstract Results of X-ray fluorescent measurements of carbon–fluorine compounds are presented. We have measured carbon and fluorine K α X-ray emission spectra (2 p →1 s transition) of graphite fluorides ( CF ) n and ( C 2 F ) n . We found that carbon atoms are of the sp 3 type and covalently bound to fluorine.

Intercalation of halogen fluorides into graphite

Journal of Fluorine Chemistry, 1978
Abstract IF 7 intercalates into graphite accompanied by the partial fluorination of the graphite host. The intercalated species was identified as IF 5 by IR and 19 F nmr spectroscopies. Mass spectrometric analyses of the gases evolved from the intercalate showed only IF 5 and fluorocarbons.

Intercalation chemistry of graphite fluorides

Journal of Fluorine Chemistry, 1992
Abstract Graphite fluorides of the general composition CFn, with n  0.25−1.0, are found, according to X-ray diffraction and X-ray photoelectron studies, to contain graphitic zones which allow oxidative intercalation by bis(fluorosulfuryl)peroxide, S2O6F2, as well as intercalation by fluorosulfuric acid HSO3F and trifluoromethylsulfuric acid HSO3CF3.

Fluoride/fluoride and fluoride/sulfuric acid graphite bi-intercalation compounds

Synthetic Metals, 1989
Abstract Stage-2 GICs with VF 6 and TiF 6 are used as host structures for the intercalation of other more volatile fluorides such as SbF 5 , AsF 5 and WF y or of sulfuric acid. This leads to new graphite bi-intercalation compounds (GBCs) having a good regular stacking along the c-axis.

NMR and NEXAFS Study of Various Graphite Fluorides

The Journal of Physical Chemistry C, 2013
Graphite fluorides with different structural types (CyF)n (y = 2.5, 2, and 1) and room temperature graphite fluorides were studied by solid state NMR and NEXAFS. Data extracted from those two techniques are complementary, providing information about the C-F bonding and the hybridization character of the carbon atom valence states.

Discharge characteristics of graphite fluoride prepared via graphite oxide

Journal of Power Sources, 1987
The discharge performance of graphite fluoride, prepared by fluorinating residual carbon from the thermal decomposition of graphite oxide, has been evaluated. In most cases, the graphite fluoride was (CF)n. That prepared from flaky natural graphite gave a higher OCV and discharge potential than (C2F)n prepared by direct fluorination; the overpotential ...

Action of fluorides in fluorosulphuric acid on graphite

Synthetic Metals, 1980
Abstract In most cases, reacting graphite with solutions of a metallic fluoride in fluorosulphuric acids leads to the formation of a binary graphite-HSO 3 F compound. The HSO 3 FSbF 5 system differentiates itself from the others, in the neighbourhood of 50 °C forming homogeneous, first stage ternary compounds of formula C 7 (HSO 3 F) x ′ , (SbF 5 )

Electrodeposition of Zr on graphite in molten fluorides

Journal of Fluorine Chemistry, 2011
Abstract The electrochemical behavior of Zr4+ using graphite working electrode has been studied in fused LiF–NaF–ZrF4 eutectic mixture (temperature range 923–1123 K). In addition to the electrochemical profile related to the deposition/dissolution of Zr metal, the cyclic voltammograms exhibit well-defined peaks attributed to the formation of ...
