Reduced graphene oxide (rGO) is obtained from chemically or thermally treated graphene oxide. Generally, preparation of rGO occurs between graphite sheets and oxidized graphene oxide. Hydrazine, hydrazine hydrate, l-ascorbic acid, and sodium borohydride are the most prominently used reducing agents for...
摘要: This paper describes a novel approach to the preparation of reduced graphene oxide and its dispersions in organic solvents. Graphite oxide, graphene oxide, and reduced graphene oxide have been prepared and characterized by a variety of physicochemical techniques....
Graphene (GO) to reduced Graphene Oxide (rGO): Preparation Graphene oxide (GO) is produced from graphite powder using modified Hummers’ technique27: A round bottom flask is kept in an ice bath and filled with 120.0 mL H2SO4(95%). Graphite powder (5.0 g) and NaNO3(2.5 g) are...
An in situ strategy for fabrication of reduced graphene oxide/fused silica (rGO/FS) composites using 3-aminopropyltriethoxysilane as surfactant is reported. GO nanosheets were bound to FS particles by an electrostatic assembly between ultra thin negatively charged GO sheets and positively charged amino...
