Abstract

The invention provides a method for electrochemically preparing boron-doped graphene through double graphite electrodes, and belongs to the technical field of controllable preparation of graphene materials and doping control of the graphene materials. The boron-doped graphene is prepared in one step by taking an aqueous solution of a soluble salt of which anions contain boron elements as an electrolyte and graphite foil as a raw material and adopting a double-graphite-foil electrochemical stripping method. As double graphite foils are used as positive and negative electrodes respectively, theuse of noble metal electrodes is reduced, and the cost is effectively reduced. The method can be simply implemented in a common beaker or glassware. The preparation method is green and environment-friendly, equipment is simple, operation time is short, operation is convenient, the process is simple and easy to amplify, and the prepared boron-doped graphene has the advantages of being high in quality, good in conductivity, excellent in dispersity in water and the like.

Description

technical field [0001] The invention relates to the technical field of controllable preparation of graphene materials and doping control thereof, in particular to a method for preparing boron-doped graphene by electrochemical stripping of double graphite electrodes. Background technique [0002] Graphene is a two-dimensional layered material composed of a single layer or few layers (less than 10 layers) of carbon atoms. By changing the size or structure of graphene, the properties of graphene can be further tuned and its applications expanded. Among them, heteroatom doping can effectively regulate the energy band structure, electrical and electrochemical properties of graphene, and expand the application fields of graphene. Therefore, the controllable preparation and performance regulation of doped graphene has become a research frontier and hotspot in the field of materials science. [0003] At present, graphene doping methods can be divided into two categories, namely in...
