摘要: 近红外光能量占太阳能的44%,但是传统半导体光催化剂难以利用近红外光,因此制备近红外光催化剂是近几年来的研究热点。本文阐述了镧系离子掺杂的近红外光催化剂催化的基本原理,综述了镧系离子掺杂上转换纳米材料/半导体复合近红外光催化剂的合成方法及特点,重点介绍了外延生长法,静电纺丝法与化学组装法。并对这些近红外光催化材料在光降解污染物和光解水领域的应用进行了总结并对其应用前景进行了展望。

Abstract: Traditional semiconductor photocatalysts are not activated by near infrared light but ultraviolet (UV) light. Owing to 44% of the incoming solar energy for near infrared (NIR) light, it's one of the hottest research topics for fabricating the photocatalysts driven by NIR light in the past few decades. In this paper, we have demonstrated the photocatalytic principle and reviewed the synthetic techniques for the fabrication of the lanthanide ions doped upconversion nanomaterials/semiconductors composited photocatalysts. The synthetic techniques including epitaxial growth, electrospinning and chemical assembly have been discussed carefully. We also have highlighted the important applications in photodegradation of wastewater and photoelectrochemical (PEC) water splitting for these photocatalysts. Furthermore, the applications of this kind of photocatalysts driven by NIR light in the future are prospected.
Keywords: near-infrared light-driven photocatalysts  lanthanide ions doping  composite materials  synthetic methods
