Scientists have turned the air into fuel

Alternative energy and the creation of fuel that is safe for the environment and at the same time high-quality, sometimes causes scientists to come up with very elegant ways of obtaining. For example, Korean researchers recently presented the technology of producing fuel from the air. And this is not a figure of speech, but the real technology described in the journal Nature Communications.

A group of chemists from South Korea created a nanomaterial capable of converting atmospheric carbon dioxide to methane, using only the energy of sunlight for this. According to one of the authors of the study, Hyundzhun Sun from the KAIST Institute,

“Our catalyst is difficult to compare with other types of similar nanoparticles, since all such experiments were conducted under very different conditions. Nevertheless, even now we can say that it has a record high level of activity and efficiency, and in some cases exceeds competitors. Other similar catalysts created in recent years have two major drawbacks that prevent them from being used in practice: their operating speed is often extremely low, and faster catalysts are usually unstable and must be cleaned after several hours of use. In addition, they all have a fairly low efficiency factor. “

The invention of South Korean specialists is devoid of these shortcomings. During experiments on nanoparticles of zinc oxide and combining them with other nanomaterials, scientists observed how their chemical and optical properties change. During these experiments it was possible to find out that the combined nanoparticles from zinc oxide and copper oxide actively absorb CO 2 molecules , decompose and convert carbon dioxide into methane under water and under good illumination. In addition, these nanoparticles were not destroyed and did not become contaminated with prolonged use.

Now experts are focused on further studying and improving the technology in order to increase the efficiency of the reactor and to establish the production of industrial plants to obtain an almost inexhaustible source of energy.
