由于纳米尺度上出现的独特性质，人们对纳米材料的研究兴趣不断增长。虽然结晶纳米材料因在各个领域表现出最先进的性能而受到关注，但近年来，由于其独特的结构特征，它们的非晶对应物也引起了人们的关注。简而言之，非晶纳米材料在原子尺度上只有短程有序，其原子堆积缺乏长程周期性排列，其中配位不饱和环境、各向同性原子结构和调制的电子态都有助于其在各种应用中的优异性能。鉴于其有趣的特性，我们在此提出了一系列的代表性工作，阐述了无定形纳米材料的结构优势，以及其增强的电催化，表面增强拉曼散射（Sers），和机械性能，从而阐明了潜在的结构-功能关系。我们希望，这种拟议的关系将是普遍适用的，从而鼓励未来的工作在设计的非晶材料，在广泛的领域表现出有前途的性能。
There is ever-growing research interest in nanomaterials because of the unique properties that emerge on the nanometer scale. While crystalline nanomaterials have received a surge of attention for exhibiting state-of-the-art properties in various fields, their amorphous counterparts have also attracted attention in recent years owing to their unique structural features that crystalline materials lack. In short, amorphous nanomaterials only have short-range order at the atomic scale, and their atomic packing lacks long-range periodic arrangement, in which the coordinatively unsaturated environment, isotropic atomic structure, and modulated electron state all contribute to their outstanding performance in various applications. Given their intriguing characteristics, we herein present a series of representative works to elaborate on the structural advantages of amorphous nanomaterials as well as their enhanced electrocatalytic, surface-enhanced Raman scattering (SERS), and mechanical properties, thereby elucidating the underlying structure–function relationship. We hope that this proposed relationship will be universally applicable, thus encouraging future work in the design of amorphous materials that show promising performance in a wide range of fields.
