Imagine a situation in which cars with internal combustion engines, thermal power plants on coal and gas and industrial plants instead of carbon dioxide when burning fuel suddenly began to produce pure oxygen. Fantastic? But it is possible, said scientists from Australia, and presented a plant for the simple and efficient conversion of CO 2 to oxygen and solid 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.
In an article in the journal Advanced Materials describing the study, the scientists reported that the compact unit was converting 100 ml of CO 2 every minute without changing characteristics for a month . To convert a ton of CO 2 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. To commercialize the technology, LM Plus was immediately established. We are waiting for interesting news from her.
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.
