Abstract

Hexagonal Ag-Pt nanoshells were prepared by using a hexagonal Ag nanoplate as the displacement template and by introducing Pt ions. The prepared Ag-Pt nanoshells played the role of an electrocatalyst in an oxygen reduction process. Compared to spherical Pt and Ag-Pt nanoparticles, the hexagonal Ag-Pt nanoshells showed higher activity for oxygen electroreduction.
