Recent Progress in Preparation and Sensing Application of Black Phosphorus-based Nanomaterials

黑磷是一种新型的二维材料,具有独特的蜂窝褶皱结构、良好的生物相容性、较高的载流子迁移率以及可调的带隙,在传感中展现了巨大的潜力。但单独的黑磷在空气中易被氧化,这限制了其应用。黑磷纳米复合材料的构建不仅有利于提升黑磷稳定性,而且有利于增强材料传感性能。该文综述了黑磷复合材料的制备及其在传感中的研究进展。首先介绍几类黑磷复合材料的制备方法,包括黑磷/金属氧化物、黑磷/金属硫化物、黑磷/单层材料、黑磷/金属纳米粒子和黑磷/碳等复合材料。然后,介绍黑磷复合材料在电化学传感和气敏传感的研究进展。最后,对黑磷复合材料在传感领域的发展与面临的挑战进行了展望。

As a new two-dimensional material,black phosphorus(BP)has been the focus of research in sensing because of its good biocompatibility,high carrier mobility and adjustable band gap.However,black phosphorus is easily oxidized in the air,which limits its application.BP based nanomaterials can not only improve the stability of BP,but also enhance the sensing properties of materials.In this paper,the preparation of BP based materials and their recent progress in sensing were reviewed.Firstly,the preparation of BP based nanomaterials,including BP/metal oxide,BP/metal sulfide,BP/monolayer materials,BP/metal nanoparticles and BP/carbon composites,was discussed.Then,the research progress of BP based nanomaterials in electrochemical sensing and gas sensing were reviewed.Finally,the development and challenges of BP based nanomaterials in the sensing field were prospected.
