Abstrakt: Techniques to control metal particle size in a supported catalyst, where metal particles may be fixed on a support by forming chemical bonds with oxygen atoms in a support, were investigated. The effect of metal particle size on a reaction selectivity was elucidated in terms of the ratio of numbers of the edge and corner atoms to those of the surface total atoms in the metal crystallites.
