金属纳米颗粒（NPs）显示出有趣的光学和催化性质，这取决于其组成、大小、形状和结构。这些NPs及其性质通常由NPs本身的对称性来定义，许多种子介导的金属NPs合成在种子和所得NP之间保持相同的对称性。然而，最近的研究表明，在种子介导合成过程中，通过明智地控制反应条件，NPs的对称性可以以一种确定的方式降低。这种能力提供了独特和可调的光电和催化性能。从这个角度来看，我们概述了通过种子介导方法获得对称性降低的NPs的一般途径，以及这种对称性降低导致的有趣的光学和催化性质。
Metallic nanoparticles (NPs) display interesting optical and catalytic properties that depend on NP composition, size, shape, and architecture. These NPs and their properties are often defined by the symmetry of the NPs themselves, with many seed-mediated syntheses for metal NPs maintaining the same symmetry between the seed and the resulting NP. However, recent research has shown that the symmetry of NPs can be reduced in a defined manner during seed-mediated syntheses through judicious control of reaction conditions. This ability offers unique and tunable optoelectronic and catalytic properties. In this Perspective, we outline general pathways to obtain NPs with reduced symmetry by seed-mediated methods and the interesting optical and catalytic properties that result from such a reduction in symmetry.
