Abstract

Catalyst-free graphene nanosheets without substrates were synthesized using pure solid carbon sources of multiwalled carbon nanotubes (MWCNTs) and a spark plasma sintering (SPS) process. Single and few-hundred-nanometer graphene nanosheets were formed from gas-phase carbon atoms which were directly evaporated from MWCNTs at a local high temperature.

摘要

使用多壁碳纳米管（MWCNTs）等纯固态碳源，通过火花等离子烧结（SPS）工艺合成了无基底的非催化石墨烯纳米片。气相碳原子在局部高温下直接从 MWCNTs 中蒸发，从而形成了单原子层和数百纳米厚的石墨烯纳米片。
