Photocatalysts are expected to contribute to the sustainable development of human society due to their ability of converting solar energy to chemical fuel and removing environmental contamination. In principle, photocatalytic efficiency is intimately related to the availability of sunlight, and thus it is vital to extend the light absorption range to the low-energy near-infrared (NIR) region. A great deal of effort has been devoted to exploring NIR-driven photocatalysts and consequently various light antennas have been reported, which can be coupled with wide bandgap semiconductors to form heterojunctions. In this review, recent progress in NIR-driven heterojunction photocatalysts is summarized, introducing in detail the variety and functionality of four types of light antennas including dyes, up-conversion carbon-based quantum dots, plasmonic materials and narrow bandgap semiconductors. This review emphasizes the effects of the heterojunction structure on the photocatalytic properties and summarizes the representative research results of NIR light antennas, aiming to promote the exploration of novel NIR light harvesting materials.

光催化剂具有将太阳能转化为化学燃料和去除环境污染的能力，有望为人类社会的可持续发展做出贡献。原则上，光催化效率与阳光的可用性密切相关，因此将光吸收范围扩展到低能近红外 (NIR) 区域至关重要。大量的努力致力于探索 NIR 驱动的光催化剂，因此已经报道了各种光天线，它们可以与宽带隙半导体耦合形成异质结。在这篇综述中，总结了近红外驱动异质结光催化剂的最新进展，详细介绍了四种光天线的种类和功能，包括染料、上转换碳基量子点、等离子体材料和窄带隙半导体。本综述强调异质结结构对光催化性能的影响，总结近红外光天线的代表性研究成果，旨在推动新型近红外光捕获材料的探索。
