Intercalation of CuCl2 into expanded graphite

Graphene-like nanosheets synthesized by natural flaky graphite in Shandong, China

“…Exfoliated graphite (EG) was first prepared from natural graphite [12]. Generally, the graphite intercalation compound could be easily synthesized in natural graphite of small particle size [12,13].…”

Epoxy Resin/Graphite Electrically Conductive Nanosheet Nanocomposite

“…The expanded graphite, (Fig. 1a) is in vermicular or wormlike shape, possessing many closed and open pores of various sizes ranging from 10 nm to 10 µm [14,17,18]. Moreover, as reflected by SEM, graphite sheets with a thickness less than 100 nm are rarely found on the surface of the exfoliated expanded graphite; the thickness of graphite sheets on the surface of expanded graphite ranged from 100 nm to 400 nm.…”

“…Preparation of expanded graphite. Expanded graphite (EG) was fabricated according to the literature [11,12]. Brief procedures were as follows: natural flake graphite was treated with a mixture of concentrated sulfuric acid and fuming nitric acid (4:1, v/v) under ambient temperature to prepare the graphite intercalation compound (GIC); after 24 h of reaction, the mixture was filtered, washed with sufficient amount of distilled water to remove excess acid, and then dried at 100 C to remove the remaining water in the following step; the resulting GIC, in the final step, was subjected to rapid heating at 1050 C for about 20 seconds to yield expanded graphite.…”

Preparation of graphene encapsulated copper nanoparticles from CuCl2-GIC

“…The starting CuCl 2 -GIC material was prepared by the classical molten salt method [15] in which CuCl 2 reacted directly with graphite powders (15 mm in average diameter). After reaction, the product was washed with ethanol/water mixture and dried at 80 1C for the later X-ray diffraction (XRD) study and reduction experiment.…”
