Carbon dioxide to oxygen and carbon

Researchers from the University of Queensland School of Chemical Engineering, led by a team from the University of New South Wales, along with researchers from the University of California at Los Angeles (UCLA), North Carolina State University, RMIT, the University of Melbourne, Queensland University of Technology, and the Australian Synchrotron (ANSTO) have found a solution efficient conversion of carbon dioxide into oxygen and solid carbon.

The experimental setup with a volume of two liters is based on physicochemical phenomena associated with the transmission of carbon dioxide through gallium. It is a so-called liquid metal that begins to melt at temperatures close to 30 ° C. In addition to gallium in liquid form and gallium in the form of nanoparticles, nanosized silver rods are added to the mixture. During operation, the mixture is intensively mixed, which causes triboelectrochemical reactions, when substances in a liquid state begin to interact more actively with the surfaces of solid fillers due to the friction force.

In an article in the journal Advanced Materials describing the study, the scientists reported that the compact unit was converting 100 ml of CO2 every minute without changing characteristics for a month. To convert a ton of CO2 into pure oxygen and solid carbon, 230 kWh of electricity was spent, which is approximately equal to $ 100. The conversion efficiency has reached 92%. Carbon, by the way, is formed in the mixture in the form of flakes and simply floats to the surface, where it is very easy to collect.

Scientists believe that such installations can be equipped with every car with an internal combustion engine and every fossil fuel power plant, and then the air will freshen up literally before our eyes. LM Plus was created to commercialize the technology.

Speaking at the G20 summit via videoconference, Russian President Vladimir Putin told the G20 leaders how to fight inflation. It is necessary to spend less on stimulating the economy and collect more taxes, the president said.

“Excessive incentives have turned into general instability, rising prices for financial assets and goods in certain markets — energy, food, and so on. The underlying cause of these phenomena is severe budget deficits in developed economies. This is the root cause, ”Putin said (quoted by TASS).

In Russia, according to Putin, this is already being done: the budget has become surplus, and monetary policy is normalizing. The Central Bank of the Russian Federation has raised its key rate at a record level since 2014 (from 4.25% to 7.5% per annum), and the Ministry of Finance has collected 1,443 trillion rubles more in the federal budget in 9 months than it has spent.
