The nitrogen doped carbon material is prepared by a nitrogen source and a carbon source through employing a hydrothermal method with one step synthesis, the preparation method comprises the following steps: weighting the nitrogen source in a three-neck flask, adding distilled water, heating and stirring to dissolve the nitrogen source, weighting the carbon source, adding distilled water for shaking and then moving to the three-neck flask, continuously stirring, performing polymerization on a reaction system at a constant temperature, moving a performed polymer system to a gallipot in polytetrafluoroethylene in a reaction vessel, performing centrifugation on the obtained product after hydrothermal carbonization, placing the separated sediment in a baking oven, and cooling to the room temperature to obtain the nitrogen doped carbon material. The carbon material is prepared by a hydrothermal method with one step synthesis, the reaction condition is wild, the step is simple, the equipment requirement is low, the production cost is reduced, and the nitrogen content of the prepared nitrogen doped carbon material is high, the nitrogen doped carbon material has large surface area, and provides guarantee for good applicability.

Description

technical field [0001] The invention relates to a carbon material and a preparation method thereof, in particular to an N-doped carbon material and a preparation method thereof. Background technique [0002] The diversification of carbon material structure and its excellent energy storage, adsorption, loading, catalytic and other properties have attracted the attention and research of many scholars. In recent years, carbon materials have been widely used in many fields such as environmental protection, chemical industry, aerospace, biomedicine, etc. application. Compared with pure carbon materials, carbon materials modified by heteroatom doping show better performance in some aspects, and are more deeply applied in corresponding fields. [0003] At present, N-doped carbon materials are an important aspect of research on atomic doping modification of carbon materials. Compared with C atoms, N atoms have one more electron in the outer layer. Therefore, compared with pure car...

Problems solved by technology

[0006] Combining the above methods, there are the following problems: (1) most of them are high-temperature reactions, and the conditions are strict; (2) most of them are multi-step reactions, and the operation steps are cumbersome; (3) most of the nitrogen atoms are located on the surface of the carbon material and the doping amount is not high. High, easy to cause damage and loss, thereby reducing performance; (4) raw materials are mostly petrochemical products, high cost
