Outline of Final Research Achievements

The reactivity of gas-phase multi-element clusters was investigated aiming for exhaustive search of promising combinations of elements and compositions for exhaust gas catalysts. In line with this objective the behavior in post heating and the reactivity to small gaseous molecules (nitric oxide) of copper and cerium oxide clusters was measured. It was found that reaction temperature range of oxygen desorption and estimated activation energy of desorption correlate significantly with the deviation from the stoichiometric composition. In addition, the reactivity toward small gaseous molecules also correlates with the deviation from the stoichiometric composition. This study showed that this gas-phase temperature programmed desorption of multi-element clusters provides new information on activation energy barrier comparable to other experimental and theoretical studies.
