| Summary: | Graphene-based composites have received a great deal of attention in recent year because
the presence of graphene can enhance the conductivity, strength of bulk materials and help create
composites with superior qualities. Moreover, the incorporation of metal oxide nanoparticles such
as Fe3O4 can improve the catalytic efficiency of composite material. In this work, we have
synthesized a composite material with the combination of reduced graphene oxide (rGO), and Fe3O4
modified tissue-paper (mGO-PP) via a simple hydrothermal method, which improved the removal
efficiency of the of methylene blue (MB) in water. MB blue is used as the model of contaminant to
evaluate the catalytic efficiency of synthesized material by using a Fenton-like reaction. The
obtained materials were characterized by SEM, XRD. The removal of materials with methylene blue
is investigated by UV-VIS spectroscopy, and the result shows that mGO-PP composite is the
potential composite for the color removed which has the removal efficiency reaching 65% in acetate
buffer pH = 3 with the optimal time is 7 h. |
