Production method of Quantum Dots of Carbon and Graphene oxide by submerged arc Discharge

摘要

p is a method of producing Quantum Dots of Graphene oxide and carbon, generating an electric arc Discharge with a current greater than 27,Between Graphite Electrodes which are immersed in a Polar Liquid, extracting and Separating between the Nanostructures cited within the liquid.In the procedure the cathode or Anode, or both are continuously replaced during the discharge process, and the polar Liquid is DISTILLED WATER, Deionized water,Filtered water or an aqueous solution of salts, which are chilled or circulated during Arc Discharge.At the end of the download allow to settle and then choose the material that floats on the surface of the liquid and the material precipitates.Then the suspension is subjected to a process of extraction of Graphene oxide dispersed within it through one of the following Procedures: Increasing the Ionic strength of the líquGone, by centrifugation, by molecular Exclusion Chromatography, using nuclear Filters using Surfactant sdbs and Nitrocellulose Filters.Chemical or other Operations that keep Quantum Dots carbon suspension. The obtained products are washed and dried at 80 degrees centigrade. / p
