From Graphite to Graphene Oxide and Graphene Oxide Quantum Dots
Small, 2017Many methods have been reported for synthesizing graphene oxide (GO) and graphene oxide quantum dots (GOQDs) where a tedious operational procedure and long reaction time are generally required. Herein, a facile one‐pot solvothermal method that allows selective synthesis of pure GO and pure GOQDs, respectively is demonstrated.

Synthesis, dispersion, and cytocompatibility of graphene oxide and reduced graphene oxide
Colloids and Surfaces B: Biointerfaces, 2012The synthesis, characterization, and toxicity of graphene oxide and reduced graphene oxide are reported. Prior to the cytocompatibility tests the stability of the suspensions in a wide range of concentrations (3.125-100 μg/mL) of three different dispersants is studied.

Effects of oxidation on the defect of reduced graphene oxides in graphene preparation
Journal of Colloid and Interface Science, 2015The 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, 2013A 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.

SINTESIS GRAPHENE OXIDE DAN REDUCED GRAPHENE OXIDE
PROSIDING SEMINAR NASIONAL FISIKA (E-JOURNAL) SNF2016 UNJ, 2016Graphene oxide (GO) and reduced graphene oxide (rGO) have been synthesized chemically from graphite powder. Graphite powder was oxidized with strong oxidator agent molekul to get graphite oxide, this process was called by Hummer’s methode. Graphite oxide was dispersed in water with ultasonic vibrator to exfoliated graphite oxide layers, and ...
