Resumo
In the present work, attempts of reducing a graphene oxide powder using a low
temperature hydrogenation disproportionation desorption and recombination process
(L-HDDR) has been carried out. A lower processing temperature in large scale
production is significant as far as costs are concerned. Graphite oxide was prepared
using a modified Hummers’ method and dispersed in ethanol, exfoliated using
ultrasonication to produce Graphene Oxide (GO). Investigations have been carried out
by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The experimental
results of L-HDDR processing graphene oxide powder using unmixed hydrogen at
400°C and relatively low pressures (<2 bars) have been reported. X-ray diffraction
patterns showed a reduction of graphene oxide with the L-HDDR process. The results
showed that the L-HDDR process, as the standard HDDR process, can be applied to
the reduction of graphene oxide to produce supercapacitor materials. The advantage
of employing the L-HDDR process is a relatively a low temperature would reduce the
cost of treatment that is a very important factor for producing large amount of material.
Thus, the L-HDDR process has been considered a promising alternative method of
reducing graphene oxide with efficiency and possibly in large scale production.
