Abstract

A facile large-scale preparation of Pt hollow nanospheres (see TEM image) makes use of Co nanoparticle as sacrificial templates. The nanospheres exhibit enhanced electrocatalytic activity. This method has been extended to the fabrication of industrially potentially useful Au, Pd, and other mono- and multimetallic hollow nanospheres.
