In this study, graphene oxide (GO) was prepared from graphite by improved Hummers
method. Graphene aerogels (GAs) were synthesized from GO by chemical reduction in
which ethylenediamine (EDA) was used as a reducing agent. Influences of conditions on GA
synthesis including content of EDA, reduction temperature and time were investigated. The
structure and morphology of GAs were studied by density, Fourier transform infrared
spectroscopy (FTIR), X-ray diffraction (XRD), Raman spectroscopy, scanning electron …
