Making Graphene Directly from CO2

Making Graphene Directly from CO2

Author: ChemistryViews

Narayan Hosmane and co-workers, Northern Illinois University, USA, have discovered a simple method for producing high yields of graphene by burning magnesium metal in dry ice — a common experiment, but one where the products have not been fully characterized until now. The team has shown that graphene was formed in few-layer nanosheets up to 10 atoms thick. The material was characterized by Raman spectroscopy, energy-dispersive X-ray analysis, X-ray powder diffraction, and transmission electron microscopy.

Graphene has been synthesized by various methods utilizing hazardous chemicals and tedious techniques. This new method is simple, green, and cost-effective. The authors note that this method not only provides a route to graphene, but is also a method of carbon capture that directly converts CO2 into a material with main potential applications.
