Size and position of metal particles on porous polymeric support were studied by transmission electron microtomography (TEMT). The porous polymeric support was prepared by ozonolysis of the polyisoprene microdomains of gyroid microphase-separated structure consisting of poly(2-vinylpryridine-block- isoprene), Then palladium metal particles were formed by reduction of Pd ions in toluene/1-propanol solvent. Pd particles on the polymer support were clearly visualized by TEMT. The size and spatial distribution of Pd particles were analyzed by 3D image analysis. Furthermore, the spatial density of Pd particles was also determined with respect to not only volume but also the surface area of the polymer support.
