在制备的2.5nm宽的FeNiPt纳米线上，通过种子介导法生长FePt，制备了单分散的核/壳结构FeNiPt/FePt纳米线（4.5 × 20-50 nm）。通过酸处理和热处理来调整FeNiPt/FePt纳米线的表面轮廓。FeNiPt/Pt皮纳米线比FeNiPt/Pt骨架纳米线具有更高的活性。
Monodisperse core/shell FeNiPt/FePt nanowires (4.5 × 20-50 nm) are synthesized by seed-mediated growth of FePt over the pre-made 2.5 nm wide FeNiPt nanowires. The surface profile of the FeNiPt/FePt nanowires is tailored by acid and thermal treatment. The FeNiPt/Pt-skin nanowires show higher activities than the FeNiPt/Pt-skeleton nanowires.
