Resumo
Graphene (G) has been attracted great interest for its excellent electrical properties.
However, the large-scale production of graphene is presently unfeasible. Graphene oxide (GO) can
be (partly) reduced to graphene-like sheets by removing the oxygen-containing groups with the
recovery of a conjugated structure. It can be produced using inexpensive graphite as raw material by
cost-effective chemical methods. Although hydrogen (mixed with argon) at high temperature
(1100°C) has been employed to reduce GO powder, the hydrogenation disproportionation
desorption and recombination (HDDR) process in particular was unreported for this purpose. In the
present work, attempts of reducing GO powder using the HDDR process have been carried out and
investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) thermogravimetric
analysis (TGA) and Fourier transform infrared spectroscopy (FTIR). The experimental results of
processing graphene oxide powder using unmixed hydrogen at moderate temperatures (about
850°C) and relatively low pressures (<2 bars) have been reported.
