The crystalline graphite sheets were successfully produced from natural graphite powder by solution-phase synthesis of graphite intercalation compounds (GICs), following a wet planetary-ball milling under mild conditions.
Other methods include explosive formation (forming detonation nanodiamonds) and sonication of graphite solutions.
Adding ecofriendly free radical initiators, in the presence of hydrogen peroxide solution leads to the expansion of graphite to graphene nanosheets.
In phosphoric acid solution (40%H3PO44), the corrosion behaviour of graphite and stainless steels was studied by the use of different electrochemical methods, namely polarization curve analysis, electrochemical impedance spectroscopy (EIS) and scanning vibrating electrode technique (SVET).
Subsequently, numerical solution of stress in IG110 graphite structure is obtained.
Catheline et al. applied volatile THF (tetrahydrofuran) to produce graphenide solutions (solutions of negatively charged graphene flakes) by dissolution of graphite intercalation compound (GIC) KC8 [30].
Attempted synthesis of the single-phase stage-2 GIC via the electrochemical oxidation of graphite in H2PtCl6 solutions failed since mixtures of the target products with pure graphite have resulted in all cases.
This is comparable to thermally reduced graphene oxide at 1,100°C in vacuum [41] and the graphene obtained by liquid phase exfoliation of graphite in surfactant/water solutions [9].
We reported the preparation of colloidal graphene in quantity via the anodic exfoliation of graphite in (NH4 2SO4 aqueous solution.
Graphene oxide solution was prepared by mixing 50 mg of graphite oxide in 30 mL of ethanol followed by sonication for a period of 30 min.
