| Outline of Final Research Achievements |
The effect of atomic arrangement of bulk and surface of supported metal nanoparticle catalysts were investigated as a high-order structural effect (3D) than the conventionally investigated structural effects of particle size (1D) and perimeter (2D). The present study focused on (1) development of simple methods to control atomic arrangement of supported metal nanoparticles and (2) impact of the atomic arrangement on catalysis of supported metal nanoparticles.
In order to change the crystal structure and morphology of metal nanoparticles, we have developed gas molecule adsorption method, where supported metal catalysts are prepared by reduction pretreatment in the presence of adsorptive gasses such as carbon monoxide and ethylene. As a result, various particle structures including twin nanoparticles and nanocubes were prepared, and thereby their catalysis for oxidation and hydrogenation reactions was changed.
