| Outline of Final Research Achievements |
For the purpose of clarifying the relations between the structure of the catalyst in the gold fine particles and catalytic activity, structure analyses were carried out by electron microscopy and theoretical calculation with the investigations of the catalytic activity and electric conductivity.
We found high catalytic activity in Au/SnO2 catalyst and clarified that there was a relation between catalytic activity and electric conductivity. We also found that catalytic activity was proportional to the length of the periphery of gold on iron oxide catalyst and on strontium titanate catalyst. The interface structure was observed by the high-resolution electron microscopy including atom columns of oxygen. It was made clear that adsorption of oxygen depended on the structure in gold - titanium oxide system by the theoretical calculation.
