Scientists have found a way to convert carbon dioxide into promising nanomaterial
A scientific team from Japan, through numerous experiments, has found an effective way to convert carbon dioxide into the so-called organometallic frameworks are promising nanostructures that can be used in a wide variety of areas.
Carbon dioxide and its prospects for use
Scientists around the world are actively looking for ways to remove excess carbon dioxide, emitted into the atmosphere in huge quantities during fuel combustion, from the atmosphere.
So the option of using CO2 in fairly valuable chemical compounds and materials is one of the most promising areas in the field of environmental protection.
But due to the high inertness, as well as the increased stability of the gas, it is very difficult to carry out any chemical reactions with it in order to obtain useful products in this way. All previous attempts have required a tremendous amount of energy and do not pay off in the end.
But Japanese specialists have developed a new method for obtaining promising nanostructures - nanoparticles, which are called organometallic frameworks (MOF).
The choice of these structures was made because such materials have a fairly wide range of applications, including as biosensors and catalysts.
Also, MOCs have a porous structure, and are capable of containing a sufficiently large volume of gas and, in fact, can act as promising devices for storing hydrogen fuel.
In order to start the conversion reaction, engineers began to pass CO2 at a temperature of 25 degrees Celsius and a pressure of 0.1 MPa through a special solution that contains the molecule piperazine.
So observing the passing reaction, scientists have recorded the appearance of white microcrystalline powder IOC.
The analysis of the obtained and thoroughly dried powder, carried out using X-ray spectroscopy and nuclear spectroscopy magnetic resonance imaging, allowed scientists to make sure that the resulting powder is really the nanoparticle that scientists wanted receive.
At the same time, the analysis of MOC showed that they have a fairly large surface area, and this is despite the fact that they are, in fact, 30% made of CO2 by mass.
Now scientists are working out ways to obtain IOC on an industrial scale directly at enterprises, for example, such as coal-fired power plants.
If everything works out, then in this way it will be possible not only to reduce CO2 emissions into the atmosphere, but also allow obtaining useful material for other industries.
Scientists have already shared their work on the pages of the Journal of the American Chemical Society.
