    Abstract

    Mesoporous Pt films with controllably large-sized mesopores were prepared by using a diblock copolymer (polystyreneb- poly(ethylene oxide), PS-b-PEO) and an organic expander (polystyrene homopolymer, h-PS). With the increase in the molecular weight of PS-b-PEO, the mesopore size gradually increased. All films possess spherical cage-type mesopores irrespectively of both the molecular weight of PS-b-PEO and the use of the expander.
