▎ 摘 要
NOVELTY - Preparing Graphene Quantum Dot involves preparing electrolyte with mixture of citric acid and alkali hydroxide in water, performing chrono-amperometry with two defect-induced graphite electrodes in electrolyte at predefined voltage and predefined sensitivity for predefined period to obtain Graphene Quantum Dots from exfoliation of the defect-induced graphite electrodes. USE - Method for preparing Graphene Quantum Dot. ADVANTAGE - The method enables to prepare Graphene Quantum Dot that in simple and eco-friendly manner.
