III  Academic Achievements

 

Recently, we built an instrument containing a metal cluster source, a continuous flow reactor, and a time-of-flight mass spectrometer, which are used to study the reactivity of sub-nano meter metal clusters. We studied the reactions between 0-1nm silver or gold clusters and O2, NO or CO. The combination of these experiments and theoretical analyses points to a surprising conclusion: the reactivity of 0-1nm of silver or gold clusters were dominated by their global electronic properties (such as spins, EA etc.), and the effects of local geometries are negligible. This conclusion provide new insights into the complicated processes in many real heterogeneous catalysts.
