Almost everyone knows about the unique properties of graphene - however, one of the main reasons preventing its mass production is still its high cost: from 67, 000 to 200, 000 dollars per ton. Scientists at Rice University (USA) have developed an inexpensive and fairly effective technology for "instant" production of graphene from carbon-containing waste.
Today, 30-40% of produced food ends up in landfills, and plastic waste has become a real disaster for our civilization. Moreover, they all contain carbon - the basis of graphene. To isolate it, a team of chemists at Rice University proposed heating the starting material in a special reactor using an electric current to 2730 ° C.
As a result of the reaction, in 10 ms, chemical bonds inside the substance are broken, and carbon is converted into graphene. In this case, the evaporated side elements can be captured for subsequent use.
Most of the energy is converted, and only a small amount is scattered as light. The technology is very environmentally friendly, since it does not require additional reagents and solvents.
In the coming years, the developers intend to increase the daily productivity of their reactor up to 1000 grams.
