A novel route for the self-assembly of nanoparticles to nanospheres at a liquid/liquid interface has been developed to prepare palladium nanospheres. It has proved that the interface offers an excellent site and plays a key role in the self-assembly of nanoparticles to nanospheres. The palladium nanospheres are characterized by electron microscopy, energy-dispersive X-ray analysis, UV-visible spectroscopy, X-ray diffraction spectroscopy, and X-ray photoelectron spectroscopy. The mechanism of the self-assembly process is also proposed.
已开发出一种在液/液界面将纳米颗粒自组装成纳米球的新途径来制备钯纳米球。已证明该界面提供了一个极好的位点，并在纳米颗粒自组装成纳米球的过程中起关键作用。通过电子显微镜、能量色散X射线分析、紫外可见光谱、X射线衍射光谱和X射线光电子能谱对钯纳米球进行了表征。还提出了自组装过程的机理。
