One-Step Electrochemical Synthesis of AlO _x -Passivated Twisted-Phosphorene Nanosheets for Potentially Stable Energy Storage Devices.

ABSTRACT: Black phosphorus (BP), a promising 2D material for electronics, energy storage, catalysis, and sensing, has sparked a research boom. However, exfoliated thin-layered BP is unstable and can easily be degraded under environmental conditions, severely limiting its practical applications. In this context, a simple and cost-effective method has been proposed that involves electrochemically exfoliating BP and simultaneously electrochemically depositing aluminum oxide (AlO _x ) for passivation of the exfoliated BP. The ambient stability of the exfoliated BP is studied using a time-dependent atomic force microscope (AFM). The AlO _x capping layer significantly improves the environmental stability of BP compared to uncapped BP. The thermal stability of the resultin
