Abstract: Disclosed is a method of forming a nitrogen-doped porous graphene envelope. The method of forming the nitrogen-doped porous graphene envelope includes dissolving a nitrogen precursor in an organic precursor and then vaporizing the resulting precursor to thus simultaneously synthesize the graphene envelope and perform nitrogen doping in a single step.

Abstract: Provided is a method for preparing single-walled carbon nanotubes (SWCNTs), including the steps of: (a) depositing a metal catalyst in the form of single atom or atomic cluster on a catalyst support to prepare a single-atom catalyst or an atomic cluster catalyst; and (b) growing carbon nanotubes on the single-atom catalyst or the atomic cluster catalyst to prepare single-walled carbon nanotubes (SWCNTs). According to the method, it is possible to uniformly mass-produce single-walled carbon nanotubes (SWCNTs) having excellent heat conductivity, electroconductivity, mechanical strength, dispersibility, or the like.
