摘要: One-dimension noble nanomaterials have promising applications in many fields, and their growth pattern control is significant to property modulation. Herein, we report a facile strategy with which the of Ag on Au nanorod (NR) or decahedral nanoparticle (NP) surface can be precisely controlled various structured Ag/Au NRs synthesized. Achievement mainly attributed adjustable reaction kinetics Ag– Ag0. Slow moderate rate favor asymmetrical growth, producing Au-tipped Ag–Au–Ag NRs, respectively. In case fast rate, symmetrical dominates form. Furthermore, prepared bimetallic used as starting materials generate other novel nanostructures (nanocups, nanonails, longer NRs). The result presented here vital both exploration theory constructing not only Au/Ag system bu...
