Description
NITROGEN-DOPED CARBON MATERIAL AND PREPARATION METHOD
THEREOF
TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of materials, in particular to a nitrogen-doped carbon material and preparation method thereof.
BACKGROUND
[0002] Carbon plays a very important role in electrode materials due to excellent physical and chemical properties thereof Electrode materials are an important part of supercapacitors. The research and development of carbon materials is a vital part of the research and development of supercapacitors. As one of the hot research objects in the field of basic materials, carbon materials still have a long way to go in terms of design and discovery of breakthroughs. Herein, doping is one of the main ways to improve the properties of carbon materials. Since nitrogen doping can significantly improve the electrochemical performance of materials, the synthesis and preparation of nitrogen-doped porous carbon materials have attracted more and more attention of researchers.
[0003] Diamond is currently the hardest material known in the world, and more and more researchers began to become interested in this material when it was discovered that carbonitrides exhibited excellent mechanical properties comparable to those of diamond. In 1989, American scientists Liu and Cohen (reference: "Prediction of New Low Compressibility Solids", Science, 1989, 245, 841) used the 13-Si3N4 crystal structure as a model under the local density approximations, in which Si was replaced with C, and they theoretically proposed a 13-C3N4 crystal for the first time, which has a hardness comparable to that of diamond. Recently. Huang et al. (reference: "Tuning Nitrogen Species and Content in Carbon Materials through Constructing Variable Structures for Supercapacitors", Journal of Inorganic Materials, 2021, 36, 7) modulated the type and content of nitrogen doped into the carbon material by the interaction between Si-O-Si network and alumina, so that the nitrogen content was as high as 5.29% at 1,000°C. However, the raw materials and methods used in nitrogen-doped carbon materials still require further research [0004] Chinese Patent Publication No. CN109647474A discloses a nitrogen-doped carbon material, a preparation method and use thereof With glucose as a raw material and melamine as a nitrogen source, the glucose is calcined to a certain temperature in an inert atmosphere to prepare a carbon substrate, and the calcined carbon substrate and the melamine are mixed in an aqueous solution in a certain proportion, heated. stirred, dried, and calcined at low temperature again in an inert atmosphere to obtain the nitrogen-doped carbon material. The preparation method is simple, the energy consumption is low, and the cost is low. The nitrogen-doped carbon material shows high reactivity and can selectively degrade a plurality of organic pollutants, thereby solving the technical problems of complex preparation methods of nitrogen-doped carbon materials in the prior art, high costs, and limited degradation ability of organic pollutants in the environment.
[0005] However, the cost of melamine in the above solution is relatively high, waste liquid is easily produced in the process, and the market has demands for large-scale production, further reduction of production costs and environmental protection.

[0009] 2. A preparation method of the nitrogen-doped carbon material according to claim I is provided, including the following steps: [0010] step 1, adding cyarunic chloride and NH2NR2 into distilled water, alcohol or benzene, and mixing these reagents evenly in an inert gas atmosphere to obtain a mixture A; [0011] step 2, putting the mixture A obtained in step 1 into a reactor, scaling the reactor, treating the reactor in an oven at a constant temperature of 700-800 K for 8-12 h, naturally cooling the reactor to room temperature, and letting stand for 2-5 h to obtain a powder B; and [0012] step 3, washing the powder B obtained in step 2 successively and repeatedly with alcohol, dilute hydrochloric acid and distilled water, filtering, repeating the washing and the filtering at least three times successively, and drying the powder B under vacuum at 350-450 K for 3-4 h to obtain the nitrogen-doped carbon material according to claim 1.
