摘　　要：纳米金属颗粒由于小尺寸效应、表面效应、量子尺寸效应显示出与块体材料不同的热、光、电、磁、催化等性能。纳米金属材料的性能不仅与粒子尺寸有关,而且还受到粒子形貌的影响。近年来,金属纳米粒子的形状控制合成受到了特别的关注。本文着重评述近年来金属纳米粒子形状控制合成的方法并以银为例介绍了其形状控制合成的最新研究进展。Nano-sized metal particles exhibit the unique thermal, optical, electric, magnetic and catalyzing properties comparing with those of bulk ones due to the small-size effect, surface effect and quantum size effect. The properties of metal nanoparticles are strongly dependent on their size and shape. In recent years, the shape-controlled synthesis of nano-particles has been attracting more and more attentions. The synthesis methods of controlling the size and shape of metal nano-particles （in the case of silver） are introduced in this review.
