Exhaustive studies: The exact reaction pathway of catalytic conversion of automobile exhaust gases, such as N2O and CO, into N2 and CO2 is still not completely understood. Studying this reaction at room temperature using the bimetallic oxide cluster couple AlVO3+/AlVO4+ in the gas phase shows that the active M-Ot. site is located at the Al-bound and not the V-bound oxygen atom (see scheme, Al pink).
