Carbon monoxide (CO) is an air pollutant that is mainly produced by automobiles. To get rid of it at the source, a platinum-based catalyst is introduced into automobile exhaust fumes that converts the CO into water and CO2.
It was previously known that this catalytic converter is active on hot exhaust gases. However, new research by scientists from the Laboratory for the Synthesis and Functionalization of Ceramics (CNRS / Saint-Gobain Research Provence) and the Institute for Catalysis and Environmental Research in Lyon (CNRS / Univ Lyon) has just shown that it is also at room temperature and in Presence of moisture is very effective.
Enough to open up new ways of treating the ambient air with this new type of carbon monoxide degradation, especially since the researchers have demonstrated the mechanism of action of this catalyst for the first time.
