Water-dispersable Pd@Au Core-Shell Nanorods Prepared with a Surfactant Mixture of CTAB and Pluronic Copolymers

摘要

Soft templates, which are composed of CTAB and Pluronics, are demonstrated to guide the growth of water-dispersable Pd@Au core-shell nanorods. Moire fringes, which occur through the plane-matching epitaxial growth without the rotation of planes, are widely observed with their alignment perpendicular to 110 directions. Optical absorbance measurements indicate the dominant effect of Pd cores, and the resonance peaks reside in the visible region.
