摘要： The present invention relates to a method for preparing graphene oxide by cutting an end face of a 3-dimensional carbon-based material by electrochemical oxidation and the graphene oxide prepared by the method. The method comprises: connecting a piece of a 3-dimensional carbon-based material as an electrode and another piece of a 3-dimensional carbon-based material or inert material as another electrode to the two electrodes of a DC power supply respectively, wherein an end face of at least one piece of a 3-dimensional carbon-based material serves as the working face and is positioned in contact and parallel with the liquid surface of an electrolyte solution; then electrifying the two pieces for electrolysis, during which the working zone for the end face serving as the working face is between −5 mm below and 5 mm above the liquid surface of the electrolyte solution; and intermittently or continuously controlling the end face within the working zone, such that the graphite lamella on the end face of the at least one piece of the 3-dimensional carbon-based material as an electrode is expansion-exfoliated and cut into graphene oxide by electrochemical oxidation, to obtain a graphene oxide-containing electrolyte solution. The method has a higher expansion-based exfoliating and cutting ability by oxidation, and can produce high-quality graphene oxide having fewer layers and more uniform particle-size distribution with low energy consumption and no contamination.

摘要： Graphene oxide quantum dots (GOQDs) a composite nanomaterial formed by the GOQDs with graphene and/or graphene-like structure(s), and methods for preparing them are provided. The method for preparing GOQDs comprises providing a carbon-based 3D bulk material having a graphite layer structure as an anode, positioning an end face of the material in contact and parallel with the liquid surface of an electrolyte solution, and intermittently or continuously cutting and exfoliating graphite layers at the end face by electrochemical oxidation to obtain GOQDs. The method for preparing the composite nanomaterial comprises adding powder comprising graphite and/or graphite-like layer structure(s) to a solution of GOQDs; under an assistant mechanical action of high shearing force, subjecting the GOQDs adsorbed onto the graphite and/or graphite-like layer structure(s) in the solution to a cycle of exfoliation, re-adsorption, and re-exfoliation, to obtain a composite nanomaterial formed by quasi-zero and/or quasi-two dimensional graphene and/or graphene-like structure(s) and GOQDs.
