Electrochemical Method To Prepare Graphene Quantum Dots and Graphene Oxide Quantum Dots [PDF]
ACS Omega, 2017 In this study, we present the preparation of graphene quantum dots (GQDs) and graphene oxide quantum dots (GOQDs). GQDs/GOQDs are prepared by an easy electrochemical exfoliation method, in which two graphite rods are used as electrodes. The electrolyte used is a combination of citric acid and alkali hydroxide in water.
