specific Embodiment approach 1

[0016] Specific Embodiment 1: The preparation method of graphitized carbon nanomaterials in this embodiment is completed by the following steps: 1. Pretreat the carbon source for 1 to 10 hours; 2. Add catalyst and pretreated carbon source to the solvent , stirring at 50°C and 100-300r / min stirring speed for 8h, wherein the mass ratio of carbon source to catalyst is 0.025-1:1; 3. Pre-carbonize the mixture in step 2 at a temperature of 80-450°C for 2-8h , the pre-carbonization atmosphere is air, oxygen, nitrogen, argon, helium or a mixture of several gases; 4. The temperature rises from room temperature to 400-1200°C at a rate of 1-15°C / min. Under the condition of heat treatment atmosphere, the heat treatment atmosphere flow rate is 30-2000mL / min, and the heat treatment temperature is 400-1200°C, heat-treat the product of step 3 for 10min-10h, wherein the heat treatment atmosphere is nitrogen, argon, helium, carbon monoxide, carbon dioxide, Hydrogen sulfide, hydrogen gas and a m...

specific Embodiment approach 2

[0018] Embodiment 2: This embodiment differs from Embodiment 1 in that the carbon source in Step 1 is agricultural and forestry crop extracts or agricultural and forestry wastes. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0019] Embodiment 3: This embodiment is different from Embodiment 2 in that: the agricultural and forestry crop extract is glucose, sucrose, fructose or starch. Other steps and parameters are the same as in the second embodiment.

Description

technical field [0001] The invention relates to a preparation method of carbon nanometer material. Background technique [0002] In recent years, research on carbon nanomaterials has attracted great attention from academia and business circles due to their application value in separation, energy storage, electrocatalysis, drug delivery, etc. Because graphite has high thermal stability, chemical stability, electrical conductivity, high electronic conductivity, field emission performance, and metal and semiconductor properties, carbon nanomaterials with graphite structure have greatly improved performance and can be applied to the preparation of Industrial electrodes, anode materials for lithium-ion batteries and as supports for electrochemical catalysts. In addition, the microscopic morphology of carbon materials also has a great influence on its application. For example, graphite capsules can be used as catalyst supports, dye adsorption and drug storage, and flake graphite ...
