Research Abstract

In order to elucidate the relation between structure and catalytic property, TEM observations and activity measurements were carried out for the model powder catalysts. The model structure using metal oxide substrate was also observed by TEM, and aberration corrected TEM revealed the oxygen atomic layer exist between Au and NiO substrate. In-situ TEM observations in gas atmosphere were also carried out for the Pt nano-particle and reversible structure changes were observed by introducing gases in the various temperature conditions.
