Abstract
We report a simple and facile method for the formation of mesopores inside Pt nanospheres using double hydrophilic block copolymer poly(ethylene oxide-b-vinylpyridine) as template and structure directing agent. The dissolved Pt species strongly interact with the vinylpyridine and ethylene oxide units. The reduction of the Pt species in the presence of polymeric micelles leads to the formation of uniform mesoporous Pt nanospheres.
