Embodiment 1

[0028] 2g of sodium acetate solid is placed in a porcelain boat, which is placed in the normal temperature zone of a horizontal tube furnace protected by a nitrogen atmosphere. After the tube furnace was heated to 700°C, the porcelain boat was pushed into the constant temperature zone and reacted for 120 minutes. After the product was cooled, the product was taken out, washed with deionized water, filtered, dried, and the product was collected. The XPS analysis results showed that the oxygen content was 10% (atomic percentage), and the scanning electron microscope results showed that the sample had a lamellar structure, and the thickness of the graphene-based sheet was ~4 nm.

Embodiment 2

[0030] 2g of sodium acetate solid is placed in a porcelain boat, which is placed in the normal temperature zone of a horizontal tube furnace protected by a nitrogen atmosphere. After the tube furnace is heated to 1300°C, push the porcelain boat into the constant temperature zone and react for 0.5min. After the product was cooled, the product was taken out, washed with deionized water, filtered, dried, and the product was collected. XPS analysis results show that the oxygen content is 7% (atomic percentage), and scanning electron microscope results show that the sample has a network structure, and the thickness of the graphene-based sheet is ~2.2 nm

Embodiment 3

[0032] 1.5 g of potassium acetate solid was placed in a porcelain boat, which was placed in the normal temperature zone of a horizontal tube furnace protected by an argon atmosphere. After the tube furnace is heated to 1000°C, push the porcelain boat into the constant temperature zone and react for 2 minutes. After the product was cooled, the product was taken out, washed with deionized water, filtered, dried, and the product was collected. The XPS analysis results showed that the oxygen content was 7.0% (atomic percentage), and the scanning electron microscopy results showed that the sample had a network structure, and the thickness of the graphene-based sheet was ~4.5 nm.

Abstract

The invention discloses a method for synthesizing graphene with organic acid metal salt. The method comprises the steps that a pipe furnace is pre-heated to 700-1300 DEG C, and protected by an inert atmosphere; the organic acid metal salt is placed in the pipe furnace protected by nitrogen, heated for 0.5-120min, and cooled to a room temperature; a solid product is obtained, washed, filtered and dried; and a graphene product is obtained. The method has the advantages of simplicity in operation, low cost and large-scale preparation under a formwork-free condition.

Description

technical field [0001] The invention belongs to a method for synthesizing graphene, in particular to a method for synthesizing graphene by pyrolysis of an organic acid metal salt. Background technique [0002] Graphene is a single-layer sp 2 The two-dimensional carbonaceous crystal composed of hybrid carbon has excellent electrical conductivity, mechanical properties, ultra-high specific surface area, and good passage and transport of guest molecules / ions, and has potential application value in many fields. With the deepening of research, the demand for macro-acquisition of graphene has become increasingly strong. Therefore, how to achieve large-scale preparation has become one of the urgent problems that restrict the further research and application of graphene. [0003] At present, the methods for preparing graphene that have been developed can be divided into two approaches: "top-down" and "bottom-up" approaches. Among them, the graphite oxide exfoliation method in the...
