Ultrafast, Low-Cost, and Mass Production of High-Quality Graphene.

Abstract

Fast, mass, and low-cost production of high-quality graphene, which is alluring, remains a great challenge, even though some approaches have shown potential for mass synthesis of graphene. Very recently a great breakthrough was made by Tour and co-workers (Nature 2020, 577, 647-651): in just a second, easily exfoliated and highly crystalline graphene was produced from abundant carbon-containing species by cost-effective flash Joule heating with a low energy input of 7.2 kJ per gram graphene. Such an ultrafast, economic, and scalable process for high-quality graphene production can be considered as a milestone in the graphene field and is highlighted in this article.
