MTU Professor Comes Up With Neat Discovery - Electronics Featured Graphene

HOUGHTON — At Michigan Tech, a greenhouse gas is heating up, but not in the way that you’d think. Materials Science Professor Yun Hang Hu and his team figured out a way to turn carbon dioxide into a newly developed three-dimensional .

“We developed an advanced material for use of application,” said Hu. “So, for example, we can use the material for a supercapacitor.”

In the lab, a compound of carbon dioxide and sodium is heated to 520 degrees Celsius. This reaction releases heat energy and forms the graphene sheets.

The surface of these sheets is covered with what appear to be dents, which are actually micropores. The dents can fold into larger pores to increase the surface area, allowing electrolyte ions to cling to it. This creates a reservoir for the ions and allows the electric charge to hold, solidifying the supercapacitive properties.

Hu said the graphene sheets are an important contribution to the debate on energy sources.
