A rapid and eco-friendly route to synthesize graphene-doped silica nanohybrids

In the present study, the possibility to synthesize graphene oxide (GO)-based nanohybrids with pure and O-2-doped silica nanoparticles by a rapid and easy hydrothermal process has been explored. The nanohybrids were prepared by varying the type of silica nanoparticles (average diameter 7 nm or 40 nm) and the silica/GO weight ratio. All the materials were fully characterized by spectroscopic and morphological techniques.
