Preparation method of nanoscale carbon material

Abstract

The invention discloses a preparation method of a nanoscale carbon material, which relates to the technical field of nano carbon material preparation. The preparation method of the nanoscale carbon material comprises the following raw materials in parts by weight: 10-50 parts of hydrocarbon, 10-50 parts of an oxygen element-containing compound and 1-3 parts of transition metal, and comprises the eight steps of raw material dilution, solution mixing, raw material crystallization, grinding into powder, high-temperature reaction, taking out and soaking, drying and grinding. According to the preparation method of the nanoscale carbon material, any catalyst does not need to be added in the preparation process, so that impurities in the catalyst are prevented from influencing the finished product quality and performance of the nanoscale carbon material, the stability of the prepared nanoscale carbon material is improved, the raw materials are mixed more uniformly, and the raw materials are separated out by utilizing a crystallization method after mixing, and a raw material with better purity is obtained; the molecular gaps among the raw materials can be effectively reduced, so that the raw materials are more pure while being mixed more uniformly, and the finished product quality of the nanoscale carbon material is improved.

Description

technical field [0001] The invention relates to the technical field of preparation of nano-carbon materials, in particular to a preparation method of nano-scale carbon materials. Background technique [0002] Carbon nanomaterials refer to carbon materials with at least one dimension of the dispersed phase smaller than 100nm. Carbon nanomaterials mainly include three types of carbon nanotubes, carbon nanofibers and carbon nanospheres. In the process of preparing traditional nanoscale carbon materials, Most of the preparation of some nano-scale carbon materials requires catalysts. The catalyst contains impurities, which affect the quality and performance of the finished nano-scale carbon materials, and the reaction temperature needs to be controlled during the preparation process, which in turn requires higher preparation equipment. Therefore, The cost of preparation is greatly increased, and the preparation efficiency is low, it is not suitable for mass production, and cannot...
