摘要： RGO is coupled with AgP in a novel one-pot photo-reduction technique in presence of a sacrificial agent like dry ethanol. Tests of the collected dirty green semiconducting towards adosoptive photodegradation of textile dyes showed that 4 wt. % RGO-AgP can degrade 100, 76, 98.57, 67.88, 69.92% of RhB, Rh6G, MB, CR and MO, respectively within only 5 min under VISL illumination over 1.5 g/L of catalyst.

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-dimensinal carbon-based material as an electrode and another piece of a 3-dimensinal 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-dimensinal 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-dimensinal 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： The present invention relates to a method and apparatus for producing a nanoscale material having a graphene structure. The present invention provides a method and apparatus which compulsorily introduces graphite sulfuric acid slurry and a permanganate sulfuric acid solution into a microchannel, to cause an oxidation reaction among layers of graphite, and which in particular involves applying ultrasonic waves during the reaction in the microchannel to improve expansion and delamination efficiency among layers of graphite, injecting an aqueous hydrogen peroxide solution into a reaction termination portion to terminate the oxidation reaction, and cleaning and drying the thus-obtained reaction mixture to produce graphite oxide. The present invention also provides a method and apparatus which involve supplying the thus-produced graphite oxide into a fluidized bed furnace to produce a nanoscale material having a graphene structure through delamination caused by thermal shock. According to the present invention, the risk of explosion is reduced during the production of graphite oxide, mass production of graphite oxide is enabled, and a nanoscale material having a graphene structure, physical properties equal to those of carbon nanotubes, and superior dispersibility is produced.

摘要： The present invention provides a graphene composite powder form material that is suitable for industrialized application. The graphene composite powder form material is composited by graphene materials and a high-molecular compound. The high-molecular compound is uniformly coated on surfaces of the graphene material. Any adjacent graphene materials are separated by the high-molecular compound. An apparent density of the graphene composite powder form material is larger than or equal to 0.02 g/cm 3 . Under an external pressure, the graphene materials in the graphene composite powder form material do not re-stack, and can be easily restored to original form, which benefit the storage and transportation. Besides, the graphene composite powder form material has a good compatibility in other material systems, which greatly broadens the application fields in the downstream products and successfully solves the problem in industrial application. The present invention also provides a method for making the graphene composite powder form material.
