在近年来发展起来的许多新型光催化体系中，等离子体光催化复合材料因其对太阳能的高利用效率而具有巨大的应用潜力，是目前研究最广泛的光催化体系之一。在这些复合材料中，等离子体纳米粒子（PNPs）通过局部表面等离子体共振有效地吸收太阳光，并将其转化为高能电子和附近半导体中的空穴。这种从PNPs到半导体的能量转移在整体光催化性能中起着决定性的作用。因此，其潜在的物理机制具有重要的科学和技术意义，是等离子体光催化剂领域的热点之一。在这篇综述中，我们研究了在理解等离子体光催化复合材料的能量传递过程方面的最新进展，描述了这一过程的理论基础和实验证明。讨论了影响能量传递效率的因素以及如何提高能量传递效率以获得更好的光催化性能。此外，对各种能量传递过程进行了比较，强调了它们对等离子体光催化剂高效运行的限制/优势。
Among the many novel photocatalytic systems developed in very recent years, plasmonic photocatalytic composites possess great potential for use in applications and are one of the most intensively investigated photocatalytic systems owing to their high solar energy utilization efficiency. In these composites, the plasmonic nanoparticles (PNPs) efficiently absorb solar light through localized surface plasmon resonance and convert it into energetic electrons and holes in the nearby semiconductor. This energy transfer from PNPs to semiconductors plays a decisive role in the overall photocatalytic performance. Thus, the underlying physical mechanism is of great scientific and technological importance and is one of the hottest topics in the area of plasmonic photocatalysts. In this review, we examine the very recent advances in understanding the energy transfer process in plasmonic photocatalytic composites, describing both the theoretical basis of this process and experimental demonstrations. The factors that affect the energy transfer efficiencies and how to improve the efficiencies to yield better photocatalytic performance are also discussed. Furthermore, comparisons are made between the various energy transfer processes, emphasizing their limitations/benefits for efficient operation of plasmonic photocatalysts.
