Abstract

The invention provides a nitrogen-doped graphene nanoribbon and a preparation method thereof. The preparation method of the nitrogen-doped graphene nanoribbon provided by the invention comprises the following steps of: firstly, by taking an inorganic covalent compound of iron namely ferric trichloride as a catalyst precursor and a solid nitrogen-containing organic compound as a carbon source, preparing a nitrogen-doped, iron-filled carbon nanotube by a floating-catalyst chemical vapor deposition method; next, putting the nitrogen-doped, iron-filled carbon nanotube in an oxidant solution, performing ultrasonic dispersion and then putting the mixed solution in an oil bath for heating reflux; cooling until the temperature reaches a room temperature, performing water washing until the solution is neutral; finally, performing vacuum drying to obtain the nitrogen-doped graphene nanoribbon. The nitrogen-doped graphene nanoribbon and the preparation method thereof provided by the invention are characterized in that lots of shortcomings of the prior art are overcome and the advantages of simple, environment-friendly preparation method and moderate reaction conditions are realized. The nitrogen-doped graphene nanoribbon provided by the invention can be applied to a lithium battery as an anode material.

Description

technical field

[0001] The invention relates to material technology, in particular to a nitrogen-doped graphene nanobelt and a preparation method thereof. Background technique

[0002] In 2004, Geim and Novoselov prepared monoatomic layer graphite or graphene by micromechanical exfoliation [Novoselov, et al. Science, 2004, 306(5696): 666]. The material has excellent optical, electrical, and mechanical properties, and has broad application prospects in the fields of energy, electronics, and catalysis. In addition to the micromechanical exfoliation method, the current methods for preparing graphene mainly include the reduced graphite oxide method [Park and Ruoff, Nature nanotechnology, 2009, 4(4): 217], the epitaxial growth method [Sutter, Flege and Sutter, Nature materials, 2008 , 7(5): 406], chemical vapor deposition [Li, et al. Science, 2009, 324(5932): 1312], organic synthesis [Yang, et al. Journal of the American Chemical Society, 2008, 130 (13): 4216] et al. These pre...
