黑磷烯稳定性增强研究进展

Progress on stability enhancement of black phosphorene

黑磷烯是一种新型的二维材料,具有高的载流子迁移率,可调节的直接带隙,独特的各向异性物理化学性质,在储能、光电、医药、传感器等领域具有广阔的应用前景。由于黑磷烯容易在潮湿和氧气存在的环境条件下发生氧化降解,限制了其实际的应用。综述了黑磷烯的不稳定机制并总结了相关研究者近年来针对提高黑磷烯稳定性的一些策略与方法,并介绍了本课题组在解决黑磷烯稳定性方面的工作进展,对未来提高黑磷烯的稳定性方法进行了展望。

Black phosphorene is a new type of two-dimensional material with high carrier mobility, tunable direct band gap, unique anisotropic physical and chemical properties, leading to wide application prospects in energy storage, photoelectric, medicine, sensing and other fields. However, black phosphorene is easy to be degraded at the presence of moisture and oxygen, which limits its practical applications. Therefore, how to solve the problem of phosphorene stability has become the focus of current research. In order to let researchers who just entered the field have a comprehensive understanding of this problem, the unstable mechanisms of black phosphorene were first reviewed and then several typical strategies in recent years to stabilize black phosphorene were summarized, the progress of our research group in solving the stability of black phosphorene were also introduced. Finally, on the basis of the current progress, future research directions to improve the stability of black phosphene were suggested.
