A team of researchers from the IRC "Smart Materials" are developing "nanosponges" to be used in the automobile catalysts.
The DonTR's report focuses on the research into nanocatalysts to be applied for purifying exhaust gases. The researchers from the International Research Center "Smart Materials"
are engaged in the synthesis and characterization of porous, sponge-like nanomaterials, such as zeolites and metal-organic frameworks (MOFs) which are able to absorb polluting gases. These materials are expected to improve automobile catalysts. As exhaust gas goes through tiny “sponges”, the amount of harmful emissions will be reduced. For example, toxic nitrogen oxide can be turned into ordinary harmless nitrogen.
In fact, similar research is being done by the world's leading vehicle manufacturers. However, the Rostov team's goal is to minimize the size of such materials, make them cheap and more effective. This is mainly achieved by synthesizing such catalysts without the use of precious metals.
"The shape of such a "sponge" is important for absorbing a big amount of contaminating substances. Imagine an ordinary sponge that is almost empty inside. There is some substance but it is porous, and as such, it is able to absorb a lot of polluting gases. At the same time, this sponge is not just inactive, on the contrary, it is a catalyst turning harmful exhaust gases into harmless ones which meet the Worldwide Emissions Standards", said Aram Bugaev, a junior scientist of the IRC "Smart Materials", SFedU.
