技术领域
本发明涉及一种贵金属纳米复合结构的构筑，属于合成化学领域。
背景技术
贵金属纳米材料具有优异的物理特性和化学特性，例如量子尺寸效应、表面效应、小尺寸效应以及宏观量子效应，并且在光、力、磁、电、表面催化和生物传感器等领域都有着举足轻重的作用，可以作为电极材料、仿生类材料、磁性存储类材料以及各类敏感材料等方面，都有着十分广泛的应用前景。但是贵金属纳米材料的物理性质和化学性质会受到其自身的尺寸和形貌等因素的影响。所以该领域的研究者一般都可以在合成这类金属纳米材料的过程中，然后通过调整上述的各种物理参数，进而依据人们的意愿制备出具有特定功能的贵金属纳米材料。就目前来看，研究中所发现的具有特定形貌的纳米晶体，他自身暴露在外面的晶面一般是特定的，因此这些特定的晶面所包含的原子的各种堆积方式以及数目也有差别，所以表现出来的性质也各不相同。对于贵金属纳米晶体材料来说，形貌的规则性不仅关系到外观，更重要的是对其自身性质的作用。但是，如今有关贵金属纳米材料合成还是没有实现较好的可控性，而且对于晶体的成核过程以及生长过程的机理探索的也不是十分清楚。
