Intercalation compounds of graphite*
A broad review of recent research work on the preparation and the remarkable properties of intercalation compounds of graphite, covering a wide range of topics from the basic chemistry, physics and materials science to engineering applications.
متن کاملStage-l Alkali Metal Graphite Intercalation Compounds: A First Principles Study
Using ab initio Density Functional Theory, we determine changes of the equilibrium structure of graphite due to charge transfer between the alkali intercalant atoms and the host layers. From our self-consistent calculations, we show for stage-l Li and K graphite intercalation compounds that there is a deviation from a universal relationship between charge transfer and the C-C bond length. We fi...
متن کاملNanotribological Properties of Graphite Intercalation Compounds: AFM Studies
Tetraalkylammonium salts have larger ions than metal ions, which can greatly change the interlayer space and energy, and then potentially tune the properties of graphite. In this work, various graphite intercalation compounds (GICs) have been synthesized by intercalating tetraoctylammonium bromide (TOAB) ions into graphite through electrochemical interactions under different reduction potential...
متن کاملSynthesis of Graphene Nanoplatelets from Peroxosulfate Graphite Intercalation Compounds
Ultrasonic exfoliation of expanded graphite compound obtained by cold expansion of graphite intercalated with peroxodisulfuric acid was shown to allow the creation of graphene nanoplatelets with thickness of about 5-10 nm. The resulting graphene material contained surface oxide groups. The expanded graphite intercalation compound was exfoliated by ultrasound much easier than thermally expanded ...
متن کاملSynthesis of ternary and quaternary graphite intercalation compounds containing alkali metal cations and diamines.
A series of ternary graphite intercalation compounds (GICs) of alkali metal cations (M = Li, Na, K) and diamines [EN (ethylenediamine), 12DAP (1,2-diaminopropane), and DMEDA (N,N-dimethylethylenediamine)] are reported. These include stage 1 and 2 M-EN-GIC (M = Li, d(i) = 0.68-0.84 nm; M = Na, d(i) = 0.68 nm), stage 2 Li-12DAP-GIC (d(i) = 0.83 nm), and stage 1 and 2 Li-DMEDA-GIC (d(i) = 0.91 nm)...
