Embodiment 1

[0030] Take by weighing 1.37g zinc gluconate (monomer zinc gluconate, molecular formula C 12 h 22 o 14 Zn, the same below; 3mmol), 0.58g citric acid (3mmol) were added in the polytetrafluoroethylene reaction tank, then added 70mL formamide / ammonia mixed solution (mass fraction 25% ammonia water / formamide volume ratio is 3 / 2) , placed on a magnetic stirrer, and stirred at a speed of 290 r / min to completely dissolve the solid and mix evenly. The obtained reaction system was placed in a microwave synthesizer, and the temperature was raised to 160°C at a rate of 8°C / min for reaction. After 1.5 hours of reaction, the system temperature automatically dropped to room temperature, and the obtained reaction product was filtered by vacuum filtration. Then the black solid was washed with pure water until the filtrate was colorless; the obtained black solid was dried in a vacuum oven at 90° C. for 5 h to obtain a nitrogen-doped carbon nanomaterial.

[0031] The obtained nitrogen-doped ...

Embodiment 2

[0036]Weigh 1.82g of zinc gluconate (4mmol) and 0.38g of citric acid (2mmol) into a polytetrafluoroethylene reaction tank, then add 50mL of N,N-dimethylformamide (DMF), and place in a magnetic stirrer On, stir at 350r / min to dissolve the solid completely and mix evenly. The obtained reaction system was placed in a microwave synthesizer, and the temperature was raised to 180°C at a rate of 9°C / min for reaction. After 3 hours of reaction, the system temperature automatically dropped to room temperature, and the obtained reaction product was filtered by vacuum filtration, and then The black solid was washed with pure water until the filtrate was colorless; the obtained black solid was dried in a vacuum oven at 80° C. for 10 h to obtain a nitrogen-doped carbon nanomaterial.

Embodiment 3

[0038] Weigh 0.46g of zinc gluconate (1mmol) and 0.38g of citric acid (2mmol) into a polytetrafluoroethylene reaction tank, then add 66mL of 15% ammonia water in mass fraction, place on a magnetic stirrer, and use 200r / min rotating speed Stir to completely dissolve the solids and mix well. The obtained reaction system was placed in a microwave synthesizer, and the temperature was raised to 140°C at a rate of 7°C / min for reaction. After 6 hours of reaction, the system temperature automatically dropped to room temperature, and the obtained reaction product was filtered by vacuum filtration, and then The black solid was washed with pure water until the filtrate was colorless; the obtained black solid was dried in a vacuum oven at 60° C. for 12 hours to obtain a nitrogen-doped carbon nanomaterial.

Abstract

The invention discloses a nitrogen-doped carbon nanomaterial and a preparation method thereof. The method comprises the following steps of adding zinc gluconate and citric acid into a reaction tank, adding a solvent, dissolving, uniformly mixing, putting the obtained reaction system into a microwave synthesizer, heating to a reaction temperature, carrying out a reaction, and purifying the black solid generated by the reaction to obtain the nitrogen-doped carbon nanomaterial. The novel carbon nanomaterial prepared by the method is doped with high-content nitrogen and oxygen elements and a smallamount of metal zinc element, so that the performance of the carbon nanomaterial is enriched, the variety of the nitrogen-doped carbon nanomaterial is expanded, and the possibility of further applying the nitrogen-doped carbon nanomaterial to the field of antibiosis is provided. The invention develops a novel nitrogen-doped carbon nano material, and provides a simple and feasible method for preparing the nitrogen-doped carbon nanomaterial.

Description

technical field [0001] The invention belongs to the technical field of carbon-based materials, and in particular relates to a nitrogen-doped carbon nanometer material and a preparation method thereof. Background technique [0002] Carbon nanomaterials are an attractive class of materials that have been extensively studied in the scientific community due to their diversity, low cost, and multifunctionality. Their physical, chemical, optical, and electrical properties largely depend on allotropic forms based on structure, morphology, and surface arrangement. Among numerous carbon-based nanomaterials, including carbon black, porous carbon, activated carbon, carbon fiber, graphene, carbon nanotubes, and carbon dots, have become the focus of global attention due to their unique properties. [0003] Functionalization of carbon nanomaterials can alter their surface, interfacial, and electronic properties, thereby increasing their value in many applications. The introduction of he...
