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.
尽管一些方法已显示出大规模合成石墨烯的潜力,但快速、大量且低成本地生产高质量石墨烯仍然是一个巨大的挑战。最近,图尔及其同事取得了一项重大突破(《自然》,2020年,第577卷,第647 - 651页):通过具有成本效益的快速焦耳加热,以每克石墨烯7.2千焦的低能量输入,仅需一秒钟就能从丰富的含碳物种中制备出易于剥离且高度结晶的石墨烯。这种用于高质量石墨烯生产的超快速、经济且可扩展的工艺可被视为石墨烯领域的一个里程碑,本文将对此进行重点介绍。
