Scientists at Karlsruhe Institute of Technology (KIT) in Germany are producing graphene using carbon dioxide as a raw material.
Researchers at KIT are presenting a process in which the greenhouse gas carbon dioxide together with hydrogen gas is converted directly into graphene at temperatures of up to 10,000 degrees Celsius with the help of catalytically active metal surfaces.Graphene is the two-dimensional form of the chemical element carbon, with interesting electrical properties.
Several groups at KIT have collaborated to present this method for separating graphene from carbon dioxide and hydrogen by means of a metal catalyst. In further experiments the researchers were able to produce graphene several layers thick, which could be used for applications in batteries, electronic components or filter materials.
The group’s next research goal is to form functioning electronic components from the graphene created.
