Advances in plasmonic photocatalysts for solar light harvesting and enhanced performance: A comprehensive analytical review

초록

Plasmonic photocatalysis has emerged as a promising field that integrates surface plasmon phenomena and catalytic properties, harnessing the unique features of plasmonic nanostructures to drive efficient light-induced chemical reactions. In this review, we delve into various aspects of plasmonic photocatalysts, exploring their design principles, energy transfer mechanisms, and potential applications. A crucial aspect is the significant influence of shape, size, and composition on the performance of plasmonic nanostructures. In addition, the arrangement and number of plasmonic metals, as well as their interparticle plasmon coupling, can influence greatly the local fields and resonance wavelengths, offering an excellent level of tunability. The mechanisms related to plasmonic photocatalysts are demonstrated, and highlighted the significance of the interface between plasmonic metals and semiconductors. It was noted that close proximity contact enables efficient direct energy transfer, while indirect contact via insulating layers impedes the process, emphasizing the importance of suitable design choices for optimal performance. Finally, we present a detailed comparative analysis of plasmonic-assisted photocatalysts in the context of photocatalytic dye degradation applications and highlighted the promising avenues for future research in this field.
