Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) have garnered attention in photocatalysis due to their unique features including extensive surface area, adjustable pores, and the ability to incorporate various functional groups. However, challenges such as limited visible light absorption and rapid electron-hole recombination often hinder their photocatalytic efficiency. Recent developments have introduced plasmonic nanoparticles (NPs) and junctions to enhance the photocatalytic performance of MOFs/COFs. This paper provides a comprehensive review of recent advancements in MOF/COF-based photocatalysts improved by integration of plasmonic NPs and junctions. We begin by examining the utilization of plasmonic NPs, known for absorbing longer-wavelength light compared to typical MOFs/COFs. These NPs exhibit localized surface plasmon resonance (LSPR) when excited, effectively enhancing the photocatalytic performance of MOFs/COFs. Moreover, we discuss the role of homo/hetero-junctions in facilitating charge separation, further boosting the photocatalytic performance of MOFs/COFs. The mechanisms behind the improved photocatalytic performance of these composites are discussed, along with an assessment of challenges and opportunities in the field, guiding future research directions.
金属有机框架材料（MOFs）和共价有机框架材料（COFs）因其独特的特性，包括高比表面积、可调节的孔隙以及引入各种官能团的能力，在光催化领域受到了关注。然而，诸如可见光吸收有限和电子 - 空穴快速复合等挑战常常阻碍它们的光催化效率。最近的进展引入了等离子体纳米颗粒（NPs）和结来提高MOFs/COFs的光催化性能。本文全面综述了通过整合等离子体NPs和结来改进的基于MOF/COF的光催化剂的最新进展。我们首先研究等离子体NPs的应用，与典型的MOFs/COFs相比，它们以吸收更长波长的光而闻名。这些NPs在被激发时表现出局域表面等离子体共振（LSPR），有效地提高了MOFs/COFs的光催化性能。此外，我们讨论了同质/异质结在促进电荷分离方面的作用，进一步提高了MOFs/COFs的光催化性能。讨论了这些复合材料光催化性能提高背后的机制，同时评估了该领域的挑战和机遇，为未来的研究方向提供指导。
