Anchored growth of highly dispersed LDHs nanosheets on expanded graphite for fluoride adsorption properties and mechanism.

Journal of Hazardous Materials, 2022
In this study, a new composite with layered double hydroxides (LDHs) anchored grown on expanded graphite (EG) interlayers was prepared by vacuum-assisted intercalation and hydrothermal method.

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.

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.

Electrochemical Introduction/Extraction of Fluoride Ions into/from Graphene-like Graphite for Positive Electrode Materials of Fluoride-Ion Shuttle Batteries.

ACS Applied Materials and Interfaces, 2022
A cathode material, graphene-like graphite, was developed for all-solid-state-type fluoride-ion shuttle batteries (FSBs). Fluoride ions were electrochemically introduced/extracted into/from it, and covalent C-F bonds were formed upon electrochemical ...

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.

Microwave-assisted liquid phase exfoliation of graphite fluoride into fluorographene

Chemical Engineering Journal, 2019
Fluorographene (FG), as an important class of graphene derivatives, has shown great promise in high-performance devices and lubricating materials. However, the large-scale fabrication of high-quality and impurity-free FG nanosheets still remains a main ...
