| titleOfInvention | Preparation method of nitrogen-doped graphene |
| abstract | Adding metered lime nitrogen, a carbon source and deionized water into a beaker respectively, controlling the temperature of a water bath at 60-80 ℃, stirring, adjusting the pH of a reaction material to 9-12, reacting for 3-5 h, uniformly spreading the reaction material into an enamel tray, drying, and uniformly grinding the material to obtain solid powder; transferring the solid powder into a porcelain boat, putting the porcelain boat into a tubular furnace for pyrolysis, introducing nitrogen into the furnace for protection, heating the tubular furnace to 540-580 ℃ at a speed of 1-3 ℃/min, preserving heat for 2-3 h, heating to 750-950 ℃ at a speed of 3-8 ℃/min, preserving heat for 1-2 h, then naturally cooling to room temperature, soaking the product with dilute hydrochloric acid, washing with water for multiple times until the product is neutral, and drying to obtain the nitrogen-doped graphene. The method uses cheap lime nitrogen as a raw material, and does not need to use a metal catalyst in the preparation process, thereby reducing the production cost and simplifying the production process. |
