title: Rational synthesis of Pt spheres with hollow interior and nanosponge shell using silica particles as template.
abstract: Here we report a facile and efficient method to prepare Pt spheres with hollow interior and nanosponge shell with high surface area. Such a unique Pt nanostructure can effectively improve the electrocatalytic performance of Pt catalysts by facilitating the access of electroactive species to the full-extent Pt surface.
