abstract = {For the past decade, researchers have been trying to
understand the mechanism of the thermal reduction of
graphite oxide. Because deuterium is widely used as a marker
in various organic reactions, we wondered if
deuterium-labeled graphite oxide could be the key to fully
understand this mechanism. Graphite oxides were prepared by
the Hofmann, Hummers, Staudenmaier, and Brodie methods, and
a deuterium-labeled analogue was synthesized by the Hofmann
method. All graphite oxides were analyzed not only using the
traditional techniques but also by gas chromatographymass
spectrometry (GC-MS) during exfoliation in hydrogen and
nitrogen atmospheres. GC-MS enabled us to compare
differences between the chemical compositions of the organic
exfoliation products formed during the thermal reduction of
these graphite oxides. Nuclear analytical methods
(Rutherford backscattering spectroscopy, elastic recoil
detection analysis) were used to calculate the
concentrations of light elements, including the ratio of
hydrogen to deuterium. Combining all of these results we
were able to determine graphite oxide's thermal reduction
mechanism. Carbon dioxide, carbon monoxide, and water are
formed from the thermal reduction of graphite oxide. This
process is also accompanied by various radical reactions
that lead to the formation of a large amount of carcinogenic
volatile organic compounds, and this will have major safety
implications for the mass production of graphene.},
