Abstract

The invention provides a large area nitrogen-doped carbon nano-tube paper preparation method, which comprises: (1) weighing ferrocene powder, dissolving in dichlorobenzene to form a ferrocene / dichlorobenzene carbon source solution, weighing pyridine, and mixing the pyridine and the ferrocene / dichlorobenzene carbon source solution to form a ferrocene / dichlorobenzene / pyridine mixing carbon source solution; 2) coiling an iron sheet or copper sheet substrate into a cylindrical material, placing into the quartz reaction chamber of a reaction furnace, sealing the reaction chamber, introducing argon gas to completely discharge air, and heating the reaction furnace; 3) when the temperature of the reaction chamber achieves 750-900 DEG C, adjusting the argon flow rate while introducing hydrogen; 4) injecting the ferrocene / dichlorobenzene / pyridine mixing carbon source solution into the reaction chamber, and carrying out a reaction; and 5) stopping the heating of the tubular reaction furnace, closing the hydrogen, adjusting argon flow rate to make the product be cooled to a room temperature along with the furnace, and collecting the large area nitrogen-doped carbon nano-tube paper on the substrate. According to the present invention, the nitrogen-doped structure carbon nano-tube film two-dimensional structure and the simple, rapid and large-scale preparation method can be used for the fields of new energy sources, sensors, flexible electronic devices, and the like.

Problems solved by technology

[0004] In the existing methods, many need to use substrates to regulate the growth of nanotubes to obtain nitrogen-doped carbon nanotubes with specific properties. The preparation process is not only complicated, but also the regulation methods are limited.

Not only that, the existing preparation process is also difficult to directly obtain large-area nitrogen-carbon nanotubes, so it increases certain difficulties in actual industrial production, and it is difficult to meet the needs of modern industry and technological development.
