TL;DR: Graphene sheets were produced from graphite oxide using a simple two-step process as mentioned in this paper, in which the mix is heated in an inert gas environment (e.g. N2) for a very short time to a moderate temperature (ca. 600°C). Reaction temperature selection should be consistent with the decomposition temperature of the expansion-reduction agent.

TL;DR: In this paper, self-standing graphene sheets were synthesized using microwave plasmas driven by surface waves at 2.45 GHz stimulating frequency and atmospheric pressure, where ethanol molecules were injected through a microwave argon plasma environment, where decomposition of ethanol molecules takes place.

TL;DR: In this article, microwave atmospheric pressure plasmas driven by surface waves were used to synthesize graphene sheets from vaporized ethanol molecules carried through argon plasma, where external cooling/heating was applied.

TL;DR: In this paper, the synthesis and characterization of graphene-like materials, prepared by plasma processing of graphite oxide, was described, and the reduced material obtained by this aerosol-through-plasma method was characterized by powder Xray diffraction, Raman, X-ray photoelectron and solid state 13C NMR spectroscopy, transmission electron microscopy, thermo-gravimetric and elemental analysis and surface area analysis methods.

TL;DR: In this article, a theoretical and experimental study on atmospheric pressure microwave plasma-based assembly of free standing graphene sheets is presented, which is based on introducing a carbon-containing precursor (C2H5OH) through a microwave (2.45 GHz) argon plasma environment, where decomposition of ethanol molecules takes place and carbon atoms and molecules are created and then converted into solid carbon nuclei in the 'colder' nucleation zones.
