The application scope of plasmonic nanostructures is rapidly expanding to keep pace with the ongoing development of various scientific findings and emerging technologies. However, most plasmonic nanostructures heavily depend on rare, expensive, and extensively studied noble metals such as Au and Ag, with the limited choice of elements hindering their broad and practical applications in a wide spectral range. Therefore, abundant and inexpensive nonnoble metals have attracted attention as new plasmonic nanomaterial components, allowing these nonnoble‐metal‐based materials to be used in areas such as photocatalysis, sensing, nanoantennas, metamaterials, and magnetoplasmonics with new compositions, structures, and properties. Furthermore, the use of nonnoble metal hybrids results in newly emerging or synergistic properties not observed from single‐metal component systems. Here, the synthetic strategies and recent advances in nonnoble‐metal‐based plasmonic nanostructures comprising Cu, Al, Mg, In, Ga, Pb, Ni, Co, Fe, and related hybrids are highlighted, and a discussion and perspectives in their synthesis, properties, applications, and challenges are presented.

非贵金属基等离子体纳米材料：最新进展和未来展望

等离子体纳米结构的应用范围正在迅速扩大，以与各种科学发现和新兴技术的持续发展保持同步。但是，大多数等离激元纳米结构严重依赖稀有，昂贵且经过广泛研究的贵金属，例如Au和Ag，元素的选择有限，阻碍了它们在宽光谱范围内的广泛应用。因此，大量廉价的非贵金属作为新型等离激元纳米材料组件备受关注，从而使这些基于非贵金属的材料可以用于具有新的成分，结构和性能的光催化，传感，纳米天线，超材料和磁等离子体等领域。此外，非贵金属杂化物的使用会导致新出现的或协同的特性，而这种特性是无法从单金属组件系统中观察到的。在此，重点介绍了非贵金属基等离子纳米结构的合成策略和最新进展，这些结构包括Cu，Al，Mg，In，Ga，Pb，Ni，Co，Fe及其相关杂化物，并对其合成进行了讨论和展望，特性，应用和挑战。
