—Present study is aimed to see the influence of
reaction temperature on the structural and optical properties of
reduced graphene oxide powder samples. In the present work,
aqueous solutions of graphite oxide (GO) were reduced at two
different temperatures (80 and 95°C) using hydrazine hydrate.
XRD and Raman studies showed that sample reduced at higher
temperature has lesser defects. UV-visible spectral studies
showed a blue shift in the absorption peak of GO after
reduction due to the increased structural ordering because of
restoration of sp2 carbon with temperature. More shift is
observed for the sample reduced at higher temperature. In our
work reaction temperature had a great impact on crystallinity
and optical properties of our samples. Our study establishes a
correlation between structural and optical properties of
reduced graphene oxide powder samples with temperature.
