Russian scientists have learned to grow graphene at room temperature

The scientific group of chemists from Russia under the direct supervision of A. Gromov, a professor at NUST MISIS, managed to develop a completely new algorithm for obtaining graphene, using this, it is quite acceptable to obtain multilayer films literally at room temperature. To start such a process, you just need a properly formulated mixture of sugar and sulfuric acid.

Graphene and problems of its production

Graphene is a single layer of carbon atoms, which in its structure strongly resembles the bridge structure that can be observed in honeycombs. And, perhaps, the main problem in obtaining graphene was that the growth algorithm of its sheets, dimensions and shape are extremely difficult to manipulate.

It is for this reason that engineers produce a variety of electronic devices based on graphene nanosheets literally in a "hand-held" format.

But Russian scientists have managed to implement a method for producing graphene at ordinary room temperature.

According to the representatives of the scientific group, it is not so difficult to obtain graphene by melting certain types of salts. The only snag is that for this you need to preheat the salt mixture to a rather big temperature of 500 - 700 degrees Celsius.

Thus, this electrochemical approach (with heating) is not entirely beneficial from the economic point of view. Having carried out a series of experiments, Russian scientists have established that similar reactions of obtaining graphene can be achieved at room temperature. And just enough to use a solution containing sugar and some sulfuric acid.

Experiments have shown that if a current is passed through such a solution, then on the surface particles of an alloy of aluminum and silicon, previously placed in the vessel by engineers, are covered with a layer graphene.

As the engineers explained, in such a simple way it is possible not only to apply graphene films to various micro- and nanoparticles, but also to obtain graphene powders with a sufficiently high specific surface area, which can be used to perform a wide variety of engineering tasks.
