Graphene has been proposed as a promising two-dimensional nanomaterial with outstanding electronic, optical, thermal and mechanical properties for many applications. In present work a process of dispersion of graphene oxide with ZnO nanoparticles in ethanol solution with different pH values, have been ...
Herein, we introduce a simple method to prepare hierarchical graphene with a tunable pore structure by activating graphene oxide (GO) with a two-step thermal annealing process. First, GO was treated at 600 °C by rapid thermal annealing in air, followed by subsequent thermal annealing in N2. ...
Graphite oxide is one of the main precursors of graphene-based materials, which are highly promising for various technological applications because of their unusual electronic properties. Although epoxy and hydroxyl groups are widely accepted as its main functionalities, the complete structure of graphite ...
a new way is provided for obtaining the stable imitation cellular outer membrane structure on the surface of the graphene oxide; the graphene oxide modified by the imitation cellular outer membrane structure is expected to have a wide application prospect in the fields of implants, tissue engineering...
During the synthesis of graphene oxide (GO) sheets, the exfoliation of graphite oxide (GpO) has become a key step to obtain fully exfoliated sheets, and ultrasound is typically applied. We compared the effect of using water bath or probe sonication on the morphological and chemical ...
Graphene oxide sheets get anisotropically crumpled and oriented by radial and shear forces in fast-thinning electrospun jets. On page 5763, Y. Dzenis and co-workers demonstrate that a small fraction of these nanoparticles in polyacrylonitrile precursor nanofibers can produce global improvements of the ...
The graphene oxide powder (GOP) obtained from the spray drying process often exhibits poor re-dispersibility which is considered due to the partial reduction of GO sheets. The reduction of drying temperature can effectively increase the re-dispersibility of GOP, but result in a decreased drying eff...
Graphite oxide, also referred as graphitic oxide or graphitic acid, is an oxidized bulk product of graphite with a variable composition. However, it did not receive immense attention until it was identified as an important and easily obtainable precursor for the preparation of graphene. This inspire...
Herein we demonstrate a facile synthetic method based on the famous Fenton reaction to prepare GNM, by using economically fabricated graphene oxide (GO) as a starting material. By precisely controlling the reaction time, simultaneous regulation of pore size from 2.9 to 11.1 nm and surface ...
