摘要:

低维黑磷具有直接可调节带隙结构、高载流子迁移率及良好的生物相容性等优点,使其在光催化降解领域有着不可或缺的地位,但它存在自然环境下极易被氧化和电子空穴利用率低等问题。制备稳定且高效的低维黑磷复合材料对于其实际应用有着重要的意义。本文介绍了低维黑磷的制备和低维黑磷复合材料在光催化降解领域的应用。对不同方法制备的低维黑磷的效果和光学性质的改变进行了比较,对机械剥离、化学气相沉积、液相剥离和溶剂热合成法进行了详细描述及总结。结合现有文献,对碳质、金属、半导体及其他材料和低维黑磷制备的复合材料进行了总结,并对复合材料在光催化降解领域的效果和复合后低维黑磷光学性质的改变进行了分析。提出了低维黑磷及其复合材料在制备上存在的问题,通过文中所述的复合方法及所选复合材料,对低维黑磷的实际应用进行了展望。

Abstract:

Low-dimensional black phosphorus plays an indispensable role in the field of photocatalytic degradation due to its numerous advantages, such as directly adjustable bandgap structure, high carrier mobility, and good biocompatibility, etc. However, it is sensitively oxidized under the ambient environment and electron-hole pairs are rapidly recombined, leading to low utilization rate. Therefore, to prepare the stable and efficient low-dimensional black phosphorus composites is significant for its practical applications. In this paper, the preparation of low-dimensional black phosphorus and the application of its composite in the photodegradation field were reviewed. The exfoliation effects and changes in optical properties of low-dimensional black phosphorus prepared via different methods were compared. Mechanical exfoliate methods, chemical vapor deposition methods, liquid exfoliate methods, and solvent thermal synthesis methods were described in detail. The composite materials of carbon, metal, semiconductor, and other materials as well as composites prepared by low-dimensional black phosphorus were summarized. The activities of the composites in the field of photodegradation and the optical changes of low-dimensional black phosphor composites were analyzed. The problems existing in the preparation of low-dimensional black phosphorus and its composites were presented. Through the different preparation methods of composites described in this paper, its practical applications were put forward.
