Synthesis of cobalt-tetrahydrofuran-graphite ternary intercalation compounds and its exfoliation.

Abstract

Ternary graphite intercalation compounds of cobalt metal and tetrahydrofuran (THF) were synthesized by the reaction between binary compound KC8 and cobalt chloride in THF solution at room temperature. By the so-called quenching process, residue compounds containing cobalt metal and THF were obtained. From these residue compounds, exfoliated graphite was obtained by rapid heating to high temperatures, in which minute cobalt particles were dispersed homogeneously and which could be formed to magnetic graphite sheets by compression.
