Researchers have developed a new technology for the effective conversion of carbon dioxide into solid carbon particles under room temperature. The technique can become an alternative way to purify the atmosphere.
Modern methods of combating CO2 are to compress and move to underground tanks, and the technology of its conversion to the solid requires a high temperature maintenance. These processes are ineffective and are associated with the risk of leakage, therefore are not suitable for industrial use.
The team of chemists from the Melbourne Royal University of Technology in collaboration with scientists from Germany, China and the United States has developed an electrochemical method of capturing and transforming atmospheric carbon dioxide into solid coal flakes. The researchers also created a special liquid metal catalyst, the chemical activity of the surface of which is significantly increased during electricity.
Carbon dioxide is in a chemical glass filled with liquid electrolyte with a small amount of liquid metal through which the electric current is passed. In such conditions, CO2 is slowly turning into solid carbon scales, which naturally separated from the surface of the liquid metal. This ensures the continuity of the conversion process.
Scheme of the catalytic process.
According to scientists, thus obtained carbon is able to store an electric charge, turning into a supercapacitor, so it can be used in industry. During the conversion process, synthetic fuel is synthesized as a by-product, which can also be used.
Other technology of CO2 transformation introduced scientists from the University of Rutgers. They developed electric catalysts that run from solar energy, which
