▎ 摘　　要

NOVELTY - Synthesizing graphene nanoribbons comprises preparing salt microcrystalline powder and mixing the organic compound and the salt microcrystalline powder uniformly. The organic compound generates naphthalene ring or perylene ring radicals by pyrolysis at 450-650℃. A mixed gas of protective gas and hydrogen is introduced, calcined at 450-650℃, and purified the reacted product to obtain the graphene nanoribbons. USE - Method for synthesizing graphene nanoribbons by catalysis on the surface of salt crystallites. ADVANTAGE - The method directly synthesizes the graphene nanoribbons in a simple, cost-effective, and eco-friendly manner by using sodium chloride with large reserves and easy availability as the synthesis substrate and catalyst inducer and without requiring high vacuum equipment.
