Exfoliation of black phosphorus (BP) into phosphorene has led to the discovery of its semiconducting properties and tunable bandgap, enabling its use in a range of applications including transistors, batteries, and sensors. However, BP's ambient instability poses a considerable challenge to its incorporation into functional devices. Observed changes to the surface chemistry of BP during degradation has recently provided insight into the degradation pathways. In this review, degradation mechanisms are discussed including the effect of oxidants, such as oxygen, water, and light, on BP degradation. Additionally, a comprehensive overview on the progress made in characterizing the surface chemistry of BP is provided, as well as the methods employed to enhance its ambient stability including capping layers, covalent and noncovalent functionalization, solvent passivation, and polymer‐based protection strategies. The effect of various protection strategies on the ambient lifetime of BP and their influence on the properties of BP are discussed.

黑磷的降解及其改善环境寿命的策略

黑磷(BP)剥落成磷烯导致发现了它的半导体特性和可调节的带隙,使其能够在包括晶体管,电池和传感器在内的各种应用中使用。但是,BP的环境不稳定性给将其集成到功能设备中带来了巨大挑战。观察到的降解过程中BP表面化学的变化最近提供了对降解途径的了解。在这篇综述中,讨论了降解机理,包括氧化剂如氧气,水和光对BP降解的影响。此外,还提供了有关表征BP表面化学特性的进展的全面概述,以及用于增强其环境稳定性的方法,包括覆盖层,共价和非共价官能化,溶剂钝化和基于聚合物的保护策略。讨论了各种保护策略对BP的环境寿命的影响及其对BP性能的影响。
