The impurity nanoparticle served as nucleation centers for bilayered graphene (BLG) growth and the free space between a nanoparticle and graphene served as the center of C injection for the continuous growth of the adlayer beneath the top layer.

A facile synthetic approach to selectively produce platinum nanowires and octahedra with high yield has been developed. Due to the well-defined {111} exposed facets, one-dimensional confinement effect, and their minimized edge/corner, the platinum nanowires exhibit excellent activity and superior durability towards both the oxygen reduction reaction (ORR) and the methanol oxidation reaction (MOR), compared to that of the zero-dimensional platinum octahedra catalyst and a commercial Pt/C catalyst. This suggests that such platinum nanowires can be used as high-performance electrocatalysts for future practical fuel cell applications.
