A group of researchers invented a new method of converting CO2, which works at room temperature. The technology of obtaining solid particles of carbon from gaseous CO2 introduced an international team of scientists led by experts from RMIT University (RMIT) in Australia. Reports Hvilya.
As scholars have noted, the opening will not only reduce CO2 emissions, but also allows you to create a new type of supercapacitors for electric vehicles.
“Wrap back time is impossible, but we can neutralize emissions by transforming carbon dioxide back into the coal,” said Dr. Torben Doenecke, author of a study published in the journal Nature Communications.
To convert the used catalyst from the liquid metal obtained from an alloy of gallium, indium and tin, which complements the catalytic active component, cerium.
The resulting catalyst was introduced into the flask with CO2, which is pre-bonded with a liquid electrolyte.
Under the influence of electrical discharge, the catalyst started the process of converting carbon dioxide into solid carbon flakes. They are formed on the surface of the liquid metal, where they are easy to remove, and the substance is then reused.
After the procedure is completed, the resulting material can be placed under the ground without risk of leakage. This is a major breakthrough. As explained by New Atlas, modern technologies of CO2 capture turn the gas into a liquid compound, after which it is pumped underground.
However, such a coal, after the procedure, you can use as the electrode.
“We found an additional advantage. It turned out that the carbon is capable of holding an electric charge, which means it can be used as a supercapacitor for vehicles of the future”, — said the head of research of the mandrel Esrafili-ass.
Also, the conversion process in the tank remains a by — product synthetic fuels for industrial applications.
The technology is not yet adapted for large-scale applications, but in the future it can be used for air purification from impurities produced by the combustion of hydrocarbons.
Recall that microscopic robots, which need to swallow, improving the system of drug delivery in the human body.
As reported by the portal “Znayu” British doctors proposed the use of blowflies for the treatment of wounds in the countries where the fighting is.
Also “Znayu” wrote that scientists around the world are already beginning to sound the alarm and ring the bells. The number of insects decreases exponentially.
