在氧化石墨烯（GO）片模板上制备了超薄Au纳米线和蝌蚪状纳米线。对于第一次，1.6 nm直径的金纳米线被证明含有六方密堆积（hcp）的晶畴，和蝌蚪形的纳米线表现出交替的hcp和面心立方（fcc）结构，与线厚度的变化。
Ultrathin Au nanowires (AuNWs) and tadpole-shaped nanowires are synthesized on graphene oxide (GO) sheet templates. For the fi rst time, 1.6 nmdiameter AuNWs are shown to contain hexagonal close-packed (hcp) crystal domains, and the tadpole-shaped nanowires exhibit alternating sets of hcp and face-centered cubic (fcc) structures, associated with variation in wire thickness.
