摘要
本文通过改进的多元醇法成功制备了尺寸可控、均一的立方形银纳米材料,然后在不经过任何后处理的情况下通过置换反应一锅合成了中空型的银/钯(Ag/Pd)和银/铂(Ag/Pt)纳米立方体,并用透射电子显微镜(TEM)和紫外可见吸收(UV-visible)光谱对所合成的Ag纳米立方和空心的Ag/Pd和Ag/Pt纳米立方进行了表征。
Hollow silver/palladium(Ag/Pd) and silver/platinum(Ag/Pt) nanocubes were fabricated for the first time through one-pot galvanic replacement method using Pd or Pt precursors and the template of freshly prepared Ag nanocubes,in which silver nanocubes were synthesized by a modified polyol reduction method.The compositions,sizes,and shapes of the Ag and hollow Ag/Pd and Ag/Pt nanocubes were characterized by transmission electron microscopy(TEM) and ultraviolet-visible(UV-visible) spectroscopy.
