Recent progress and challenges in plasmonic nanomaterials

Owing to their optical, mechanical, and catalytic properties, plasmonic nanomaterials (P-NMs) have been widely used in sensing, disease treatment, as well as energy transfer and conversion applications. Therefore, the synthesis, properties, and applications of P-NMs have garnered significant interest in recent decades. This review surveys the various types of P-NMs, their synthesis methods, their properties, and recent applications. In addition, we summarize the current challenges and future developments in P-NMs. We hope this article will help researchers to gain a deeper understanding of P-NM applications in the field of energy, overcome the current problems associated with P-NMs, and develop novel P-NMs with better characteristics.
