Low-Cost Production of Graphene from Coal [ID 12018]

Description:

Overview

Exploitation of the unique properties of graphene for new commercial applications is occurring at a phenomenal rate. However, current methods of graphene production are inefficient and expensive and do not provide a commercial supply to meet expected future demand. An industrially scalable production method capable of producing large quantities of low-cost, defect-free graphene is necessary to supply graphene manufacturers of the future. 

 

Ohio University researcher, Dr. Gerardine Botte, has developed a simple method of producing graphene from inexpensive and widely available coal. The process begins by subjecting ground coal to electrolysis. The  resulting coal char is used as a carbon source for graphene growth via chemical vapor deposition (CVD).

 

This approach also eliminates dependence on graphite as the carbon feedstock for graphene production. Graphite deposits are limited, with China producing 70 percent of the world’s supply. Currently there is no graphite mined in the United States, however, coal reserves are plentiful.
