Graphene has gotten a lot of hype since this 2-D form of carbon was first discovered.
Yet, despite all its potential, graphene has so far been slow to make its way into commercial production. Because, it turns out, graphene isn’t all that easy to make in large quantities at low cost.
Researchers at Kansas State University have devised and patented a simple, inexpensive, and scalable method to mass produce graphene. Using only hydrocarbon gas, oxygen, and a spark plug, the Kansas State scientists were able to simply and inexpensively make a lot of graphene—no hazardous chemicals, catalysts, or fancy machinery needed.
“We have discovered a viable process to make graphene,” lead inventor and Cortelyou-Rust distinguished professor of physics Chris Sorensen says in a Kansas State University press release. “Our process has many positive properties, from the economic feasibility, the possibility for large-scale production, and the lack of nasty chemicals. What might be the best property of all is that the energy required to make a gram of graphene through our process is much less than other processes because all it takes is a single spark.”
The researchers accidently discovered that simply adding acetylene gas and oxygen to an aluminum cylinder and detonating the mixture with a spark plug yielded something potentially even more useful than what they were hoping for. The team was trying to form carbon soot aerosol gels, but instead produced gram quantities of graphene simply, efficiently, inexpensively, and scalably.
