Solar-driven photocatalysis holds great potential for energy conversion, environmental remediation, and sustainable chemistry. However, practical applications of conventional photocatalytic systems have been constrained by their insufficient ability to harvest solar radiation in the infrared spectrum. Lanthanide-doped upconversion materials possess high photostability, tunable absorption, and the ability to convert low-energy infrared radiation into high-energy emission, making them attractive for infrared-driven photocatalysis. This review highlights essential principles for rational design of efficient photocatalysts. Particular emphasis is placed on current state-of-the-arts that offer enhanced upconversion luminescence efficiency. We also summarize recent advances in lanthanide-doped upconversion materials for photocatalysis. We conclude with new challenges and prospects for future developments of infrared-driven photocatalysts.
太阳能驱动的光催化在能源转换、环境修复和可持续化学等方面具有巨大的潜力。然而，传统光催化系统的实际应用受到其在红外光谱中对太阳能辐射的吸收不足的限制。镧系掺杂上转换材料具有高的光稳定性、可调的吸收和将低能量红外辐射转化为高能发射的能力，使其成为红外驱动光催化的理想材料。本综述强调了合理设计高效光催化剂的基本原则。特别强调了提高上转换发光效率的最新技术。我们还总结了镧系掺杂上转换材料在光催化中的最新进展。最后，我们对红外驱动光催化剂的未来发展提出了新的挑战和展望。
