Problems solved by technology

However, these reducing agents themselves are toxic or explosive, and have great hazards.
Moreover, the graphene obtained by using these reducing agents is prone to irreversible agglomeration in the solution, and it cannot be further modified and functionalized, which greatly limits its application in fields with high quality requirements for graphene.

Abstract

The invention relates to a method for preparing graphene by reducing graphene oxide based on a camellia oleifera extract and belongs to the technical field of materials. According to the method, by adopting the camellia oleifera extract procyanidine as a reductant for graphene oxide, the efficient reduction of graphene oxide can be achieved under the conditions of acidic environment and 80 DEG C water bath to prepare the graphene. Compared with the existing method for preparing the graphene, the reductant adopted in the method is derived from agricultural and forestry wastes, the system is environment friendly, safe, efficient, inexpensive, is easy to prepared on large scale and has very significant industrial application potential.

Description

technical field [0001] The invention belongs to the technical field of materials, and relates to the preparation of nano-carbon materials, in particular to a method for preparing graphene by reducing graphene oxide from camellia oleifera shell extract. Background technique [0002] The preparation methods of graphene mainly include mechanical exfoliation method, chemical vapor deposition method, directional growth method, electrochemical synthesis method and chemical synthesis method. Among them, the chemical redox method is the most suitable method for the preparation of low-cost and large-scale graphene. The chemical redox method is to oxidize graphite to graphite oxide by oxidation reaction, and then form graphene oxide by ultrasonic stripping, and then add a reducing agent for reduction. The commonly used reducing agents are hydrazine hydrate, ethyl hydrazine, NaBH4 / hydroquinone, etc. However, these reducing agents themselves are toxic or explosive, and have gr...
