2.3.3Graphene and graphene oxide Graphene is a thin 2D structure made of carbon atoms and has excellent thermal and electrical conductivity with a wide range of applications.Graphene oxideis the oxidized form of graphene, which can be prepared easily compared to graphene. Due to their significant...
(Fig.1b). As a typical example, a nanosized tin oxide@graphene cage hybrid (SnO2@GC) with 67 wt% SnO2is prepared, which is characterized by a high specific capacity (974 mAh g–1) and an ultrahigh volumetric capacity of 2123 mAh cm–3due to the well-designed void (~260...
Increasing fresh water demand for drinking and agriculture is one of the grand challenges of our age. Graphene oxide (GO) membranes have shown a great potential for desalination and water purification. However, it is challenging to further improve the water permeability without sacrificing the separat...

Graphene oxide (GO) is preferred over graphene for preparing homogeneous aqueous suspensions as the precursor for 3D GBMs [31] because the abundant oxygen-containing groups on the GO surface result in a highly hydrophilic property and avoid the irreversible agglomeration of hydrophobic graphene [32]...
We report a facile method for the fabrication of three-dimensional (3D) porous materials via the interaction between graphene oxide (GO) sheets and polyethylenimine (PEI) with high amine density at room temperature under atmospheric pressure without stirring. The structural and physical properties of ...
Nonetheless, a few attempts to date have envisioned the use of graphene for the fabrication of three-dimensional (3D) substrates for neural repair, but none of these involve graphene oxide (GOx) despite some attractive features such as higher hydrophilicity and versatility of functionalization. In ...
Finally, the 3D printed construct consisting of GO and polyvinyl alcohol (PVA) has demonstrated high conductivity, porosity, and flexibility [90]. 2.3. Reduced Graphene Oxide (rGO) rGO is an intermediate structure between graphene and GO that partially restores graphitic characteristics by removing ...
Semiconductor analog of graphene: Graphene oxide has been synthesized at our R&D facilities using modified reaction Hummer technique. Growth technique emphasizes on minimizing the defect density to yield optically active material and increasing the average grain size (flake size). Unlike many other graphe...
