The invention relates to the technical field of carbon material preparation, in particular to a preparation method and application of a nanometer carbon material. The invention provides a preparation method of nano-carbon material, which uses carbon chain polymer substances such as plastics as raw materials, and is prepared by three-stage microwave treatment under the action of microwave catalyst; in the three-stage microwave treatment, The power of the first stage of microwave treatment is ≥200W, the power of the second stage of microwave treatment is 20‑40% higher than that of the first stage of microwave treatment, and the power of the third stage of microwave treatment is 45‑65% higher than that of the second stage of microwave treatment %. The preparation method of the present invention has the advantages of low cost, high yield and high purity, and is a safe, energy-saving, environmentally friendly and efficient preparation process for nano-carbon materials, and the flammable gas rich in hydrogen, methane and other gases generated in the preparation process is The gas can be recycled again, which greatly improves the utilization rate of resources. |
