Effects of oxidation on the defect of reduced graphene oxides in graphene preparation

Journal of Colloid and Interface Science, 2015
The relationship between the defects of reduced graphene oxide (RGO) and the oxidation degree of graphite in the preparation of graphene with chemical conversion method has been studied in this work. This study was performed on an artificial graphite through the measurements of X ray diffraction, Raman spectroscopy and particle size analysis.

Electrochemically “Writing” Graphene from Graphene Oxide

Small, 2013
A novel approach of patterning graphene on conductive surfaces based on local electrochemical reduction of graphene oxide is reported. Graphene is "written" from typical graphene oxide dispersion by applying negative potential on conductive surfaces vs.

Measuring the specific surface area of monolayer graphene oxide in water

, 2020
Many applications of graphene oxide concern specific surface area. Monolayer graphene has a high specific surface area of about 2630 m2/g, but the specific surface area of monolayer graphene oxide reported in literature (usually 2–1000 m2/g) is much ...
