Canadian scientists have created a powder consisting of porous carbon nanospheres, which can effectively absorb carbon dioxide produced by the intensive enterprises and power plants.
A team of chemists from University Waterla has developed an inexpensive and environmentally friendly product to combat greenhouse gas. For the manufacture of carbon powder, only vegetable raw materials, salt and heat are required. All components are available and safe, which makes it environmentally friendly and inexpensive in production.
The developed technology makes it possible to produce spheres with a diameter of not more than 1 μm, having many voids and holes. When contacting the powder, carbon dioxide molecules stick to the carbon surface, and the nanospheres actually absorb it. After saturation, the product must be assembled and buried in special underground formations to avoid evaporation of CO2 into the atmosphere.
Scientists argue that the absorption efficiency of the created powder is twice as high as other existing methods of neutralization of carbon dioxide produced by industrial enterprises and power plants as a result of burning fossil fuels.
Driving the size and concentration of pores can be further improved by the absorption characteristics. Powder can also be optimized for water filtration, energy accumulation and other applications.
Scientists from the University of Rutgers offer another way to combat CO2 emissions. They developed
