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.
等离子体纳米结构的应用范围正在迅速扩大，以跟上各种科学发现和新兴技术的不断发展。然而，大多数等离子体纳米结构严重依赖于稀有、昂贵且经过广泛研究的贵金属，如 Au 和 Ag，元素选择有限，限制了它们在广泛光谱范围内的广泛和实际应用。因此，丰富且廉价的非贵金属已引起人们的关注，成为新的等离子体纳米材料成分，使这些基于非贵金属的材料能够在光催化、传感、纳米天线、超材料和磁等离子体等领域中得到应用，具有新的组成、结构和性能。此外，使用非贵金属杂化材料会产生从单金属成分系统中观察不到的新出现或协同特性。在这里，强调了包含 Cu、Al、Mg、In、Ga、Pb、Ni、Co、Fe 及其相关杂化的基于非贵金属的等离子体纳米结构的合成策略和最新进展，并对其合成、性质、应用和挑战进行了讨论和展望。
